Actually, it's been proven safe for 13 year olds to start lifting weights. Just that they have to start slow.
Nice workout schedule, VanK, and a great idea for a thread. I would have to recommend you putting bis and tris on the same day, and three times a week for abs max is ok. If you're looking to get bigger and still maintain your body fat %, it's not going to happen unless you start a bulking phase (gain muscle, but also gain some fat in the process) then when you're done the bulking phase, go on the cutting phase (burn a lot of fat, but lose a little bit of muscle.) These phases is the fastest way.
As for diet, you have to eat more calories than you burn if you want to bulk (and get rid of the cardio, unless you're on a cut). Eat a good ratio of carbs (avoid fructose as much as possible), protien and fats, about 33% each for now. As for the fats, stick to the monosaturated and the polyunsatured fats (such as natural peanut butter, olive oil) and avoid the saturated and trans fat. DWeaver could probably give you some good food tips. Oh, and drink a lot of water! I can't emphasize that any more.
For lifting, always go slow, it provides the safest and greatest gains, especially on the negative rep (lowering of the weight). Aim for between 6-10 reps until failure (where you can't do any more reps) in controlled and accurate movements. Change up your exercise routines every 4 weeks, or else you'll hit a plateau where your body gets used to the exercises. You need to 'shock' the muscles as much as possible.
Supplements would be beneficial to any growth, such as multivitamins, whey protien (for post work out or meal replacements), and glutamine. Creatine is optional if you want additional benefits.
And finally, lay off the heroin
