Hey Jess welcome to SM there is tons of information here for you apart from the tut suggested by Dave check out this one on blend shapes its free and will show you a brief example of the quality of tutorials you can get here. Also the forums are great for support a critic. Many have made the treacherous journey from one program or another to Maya and SM is the best site to help that transition.

Let us know if you have any specific questions.
