I think you should get poker-tracker. If you don't know already, it will soon show you that playing K7s and A2o are not good ways to make money. Etc.
Play low stakes full-ring, and play tight, adjusting for tables where everyone is crazy tight, or just crazy. Suckouts will happen, but that's why you have a bankroll. You can play four tables comfortably cos you'll only very rarely be playing two hands at once (think VPIP 18ish and you'll understand why). You'll get a lot of hands into PT reasonably quickly this way too.
