while I'm not a teacher I've found some pretty good sites for self-learning. and I have a copy of Maya 8 (which is about two version behind). Maya's official site does have some really good tutorials on this. CS4? don't look at me, I'm happy with CS2. but I do know a good site for tutorials on Photoshop (possibly some of the other programs that came with CS4 premium).
http://www.good-tutorials.com/ has some really good ones. and there are a few high level tutorials on there. (this is the Photoshop/CS tutorial site) it's expanded a bit but nothing really catches the eye for the other categories.
