B,
All the above is pretty much correct, especially from Hueypilot and Yahtzee. As a current T-37 IP and from someone who has gotten here the hard way, I would offer the following information..
My hard road to being a Pilot took me to Nav school first out of ROTC, then faced with cutbacks following the so called "peace dividend" after the fall of the Soviet Union (rest in peace our dearest and best adversary), I ended up in my hometown ANG unit for a UPT slot. Now because I like teaching so much, I am a reservist flying T-37s. I am just a glorified CFI, and I my students get paid to be prepared for each lesson, instead of me trying to manage their budgets as well as their training at the local Part 61 FBO.
You are fairly young, but at the same time have quite a bit of flight experience. You should try to open all doors and see who answers. It will probably take you two years from present to get through the active duty cycle and walk across the stage at graduation, then you will be 26 almost 27 years old with a 10 year commitment to the Air Force. I don't know if you plan or want a 20 year career. What I do know, is that in the ANG or Reserve you get to pick your plane before SUPT. You still have a 10 year commitment after UPT, but it is not exclusive to that particular unit nor does it require full time services to honor that commitment. It will probably take 2 to 3 years to find yourself at UPT for a Guard or Reserve unit from this moment, and that is due to timing of fiscal year stuff, when they interview, and when you get a UPT slot. This fiscal year slots are gone and given out, next year's beginning in October are probably already through the first round of interviews, they will probably make a final selection once they get a firm hand on the actual number of slots that particular unit is going to receive. Then those lucky few will have to get the med stuff done, get through IFT (intro flight training=Air Force pays for 50 hours for you to earn a private ticket and if you don't do it in 50 or you pink slip no UPT for you) and get commissioned, so none of them will make it a base before summer of 04. You may ask why you should take a road that may take another year to get you that pair of coveted pilot's wings?
Well, as I said your Reserve commitment is not a full time, so you graduate UPT with about 1000 hours total time, 200 multi-turbine (counting the 800 you already have), and if you are lucky enough to get that F-15/16 unit you start racking up turbine PIC right away. This makes you instantly marketable to the regional airlines assuming you don't get a regional job before you get to UPT (which opens up another good deal, you take mil leave from your job, they keep it for you, and two years later you go back to work at much better seniority and pay). By the time market turns around for the majors (if that is your goal), you'll be maybe 31 to 32 years old and searching for airline employment versus the guaranteed 37 years old that you will be if you take the 10 year commitment to active duty.
Each Guard unit is awarded their UPT slots from the Guard Bureau and has total control as to whom they are awarded. Typically each unit gets two per fiscal year sometimes more depending on needs, one will be awarded in house to somebody already within the unit such as a crew chief enlisted dude or a loadmaster/flight engineer from the enlisted aircrew force in a C-130 or C-141/17/KC-135 unit, and one will come off the street (someone with no military background). The navigators in the 141 and KC-135 units now are getting free extra slots that don't count against these numbers right now because their positions are being eliminated with the C-17 or the KC-135 avionics upgrade called "Pacer Craig" (SP on that program name?). Competition for these off the street slots is pretty stiff, my guard unit went through a stack of almost 100 guys to get to one dude for an off the street slot. What improves your chances for these "off the streeters"? Having prior flying time, already having a degree, (you can go to UPT for the Guard if you have 2 years of college, but you must promise to complete your degree within 7 years of completing flight training-this very rarely happens anymore because people were abusing the system, not getting degrees, getting jobs in the last big hiring market and then quitting the units) and having some local ties to the area. Did you grow up there, do your parents live there, do you currently live and work there, did you attend university there, meet your wife there and plan to settle near her parents etc....?
Reserve units while almost the same as far as flying and pay dates have no control over their slots. Each unit sponsors candidates to a federal selection board that meets at AFRC HQ in Dobbins. Candidates are selected for UPT, then the unit is told whether or not their candidates were selected. Sometimes units come up dry, if the candidates they sponsored were not as competitive as the other candidates. If their candidates are selected, then they get to come back and fly for that unit after UPT.
Would you or should you enlist to improve your chances with an ANG unit? Depends on what you want. Enlisting doesn't hurt your chances of getting an active duty slot. You are not breaking any commitments you had from enlisting because going to be an active duty officer is a higher commitment. Kinda like moving up from the minor leagues to the majors. Enlisting does get you a free version of the GI Bill that you can use to offset costs for additional ratings at part 141 schools (my CFI and my 737 type came courtesy of the GI Bill) if you never get lucky enough to get a UPT slot.
The quickest way for you to an Active Duty slot right now is through Officer Training School (OTS). However OTS is a backfill method of producing officers. Whatever doesn't come from the Academy and ROTC is what OTS is called on to produce each year. Sometimes it is very competitive and sometimes it is not. When times are competitive, the next way to active duty may be through the accelerated ROTC program. To do that however, you will have to go back to school and get another degree or a masters degree that you can complete in two years. I've been out of touch with my old ROTC detachment for a while so I am not as up on things as I used to be, go talk to the ROTC guys at your school, they are much less likely to feed you BS because they are not trying to fill quotas like the NCOs at the recruiting stations or find the Academy Admissions Liaison Officer for your area (they recruit for all officer sources not just the academy)
I don't know where you are, but here are some fighter units and the planes they fly off the top of my head:
New Orleans F-15 ANG and A-10 AFRES
Barksdale, LA A-10s AFRES
South Carolina F-16s ANG
Atlantic City F-16s ANG
Fresno CA F-16s ANG
Fort Worth F-16s ANG
Houston F-16s ANG
Jacksonville F-15s may have converted to 16s ANG
Willow Grove PA A-10s ANG
Otis, MA ANG
Baltimore A-10s ANG
Here are the ANG and AFRES websites list of units index:

Each ANG unit has their own individual recruiters, and the AFRES dudes work through a centralized system, you call the toll free number and get connected to the recruiter that services your region.
As one who has been in both reserve components, I would recommend the Air Guard over the Air Force Reserve if I had to choose between the two.
