I would agree with the idea of outside studying. I made the mistake early in my private of not studying. I passed my private ok but when I got into instrument, studying was really hard. There are some redundant things, but not much. It's a whole new ballgame. You'll need to spend a whole lot of time studying. Also, get the Jep book. I know it's expensive but it's the best and most comprehensive.
Also, If I were you I would try to fly out of PDK. I know it's busy but if you plan on going all the way it will be something you have to get used to. When you begin your instrument you will be glad you've had a lot of radio work. You'll have a lot to do while flying the airplane, fumbling with charts, and changing nav/com frequencies. Having a good feel for ATC will make this easier. Learn all you can now.
ALso, learn that private stuff!! I thought I was done with that stuff after I got my ticket. I am working on my mult-commercial right now and guess what? A lot of private stuff involved. You may not use much of it in the instrument phase, but you'll need it again later. Good luck.
