are there any particular cords i should learn first? currently, I think I know the G, C and D major cords (and have just recently added D minor).... i practice switching between them....

another question... i orignialy started with a pick (months ago) but now that I've gotten back into it, I'm going figure style... what's the difference, any suggestions? my father in law taught himself and has been playing for a long time (we don't live close enough for lessons)... he only uses fingers... so that caused the change.... opinions? thoughts, comments? thanks!
