RE: proper bow form
A lot of second rate bow shop people think their way of doing things is the only way, and they're almost always screwed up.
I'm afraid I don't know of any good videos or books for shooting compounds, but I'm sure they're out there. Somebody can steer you right on that, I'm sure. I just wanted to reinforce what treboryerf said... Hang out with good shooters. Don't just watch what they do, study what they do and try to incorporate some of their techniques into your own shooting style. Take what works for you and discard the rest.
Don't be afraid to ask for help. You'll run into the inevitable jerk who won't give you the time of day, but most archers are more than willing to help someone who's having trouble.
