You made a wise decision. 🙂
I’m not being flippant here–IMO the best way to learn the program is to read the manual front to back. It would probably help to get a few DVDs to give you some context (and more fun) too. I recommend all of the offerings at 3DFluff.com. There’s also a good beginner/intermediate book by Anne Powers, which I think was reviewed on this site. That should help you hit the ground running.
