Keep in mind that I'm a beginner also, but I would suggest you start with theory. TBlock has a post on this site about forming chords and he breaks it down. LG-FAMILY correct me if i'm wrong, to play the fuller chords you'ld play the 7th, 9ths and 13th chord he talks about. BUT I SUGGEST THEORY first because if you don't understand what you're forming and when to form it you may be handicapping yourself.
