The FAA publication "Pilots Handbook of Aeronautical Knowledge" for the nuts and bolts. FAA's "Airplane Flying Handbook" for the flying lesson plans. FAA's "Aviation Instructor Handbook" for the FOI stuff. FAA's "Aviation Weather" and "Aviation Weather Services" for weather topics. And don't ever forget the good ole trust AIM.
In other words, a safe bet is to always use FAA publictions (all downloadble free on their website if you don't have them already.
Some examiners will blowout a vein if you go into the checkride without using FAA materials to prepare (for atleast a big percentage of it). Especially when it comes to teaching maneuvers. One comment they always like to say is "Well, what does the FAA have to say about that? Prove it?"
With that said, don't be afraid to use supplemental materials as well. Just make sure the nuts and bolts of each plan is based on FAA material.
