The only thing I know of for the basics is the help files, when Maya is open press F1 and the help files will pop up. From there you can look up anything you want and there are little tutorials to practice with, pretty helpful to. Basically what you want to do when you're new to maya (atleast this is what I did) spend a couple weeks just messing around in it doing whatever you can, learn where things are in the program. After you have a feel for the program and where things are and what things do, then have a stab at one of the free tutorials.
