Hey you never asked me to be your guitarist
Get some chords off the net, get used to the different postions, just to get your fingers stretching. It takes time, don't worry! Even for bassists it's hard gettin the chord positions cause your not used to it. When you get used to the positions start practising sequences of chord shapes. It takes time, don't rush it!
My brother bought a book called "10 minute Guitar Workout" and it helped him a lot. It's for beginners to advanced players and there's progression guides and such like. You can get it in Virgin or off the net, obviously! Probably better than my advice! Mind you i'm an impatient teacher
Keep on rockin dude
