Welcome to the wonderful world of animation. I think Ed's covered most but I'd like to add, learn to love the graph editor. I did a brief tutorial on Poseamation a while back and put it onto my site http://www.enigmastudio.co.uk go to the tutorial section that'll save you having to trawl back through the archives. It might help explain some of the mysteries. I've now left Poseamation, but I've started a new little group on Yahoo called Flash_erotica you'd be welcome to join me there. Personally, I think Poser is the easiest of the apps to learn animation with and many of the concepts cross to the other more expensive apps.
