Autodesk's book from Jeff Unay for modeling and rigging.

Any of the Autodesk's Maya books are good.

Be ware of the none Autodesk brand books...they are not that good and a waste of money. I know, because I threw them out.

or get videos from digital-tutors.com, they r using Maya 8.5.

And the Advanced Shading and Lighting book.

Doesn't really matter, if it is 8.5 or not, the menu may be rearranged, but it is still Maya. And you can turn off the stupid 3D max display manipulators to speed up your modeling.
