Jman,
First: You are too young to be doing 1-rep max's. If you wanna know your 1-rep max use a simple calculation that you can find on the web.
B: Do not try to do fewer than 6 reps. Mass workouts will tear down your tendons along with muscles and your's are still growing.
and 3: Stick with a simple 3 sets (plus a warm-up set of 35% of your CALCULATED 1-rep max) of 8-12 reps.
If you wanna change it up sometimes, try adding chains (5 lbs each side should be good for now) to the bar as this won't over-burden your tendons, since they maximize strength as your arms are straightened out in front of you.
I would stick with large muscle groups only because of your age. Doing smaller groups won't come until you are 18 or 19. Here are the groups you could/should target: chest, shoulders (be careful and don't go to heavy on your shoulders) upper back(lats and traps), glutes, quads, hams, calves, and core (abs and lower back will be key, just go light on them at first). If you plan to play football don't neglect your neck... Exercise your neck with simple side-to-side and front-to-back movements using your hands as resistance.
You will also want to work your endurance and burst speed with running/sprinting. Look-up fartlek (snicker) on the web and open your eyes to a new world.
Good-luck,
Rip
