I think a combination of all is the best way to learn maya, i'm currently following a course in maya(in holland)
I've purchased the following books;
-advanced maya texturing and lighting by lee lanier
-learning maya 7 foundation
-learning maya the modeling and animation handbook
-maya ultimate workshop by luc petitot
-learning maya unlimited features
-the game animators guide to maya by michael mc kinley
-complete maya programming by david ad gould

I also would recommend the lynda.com tutorial==> https://movielibrary.lynda.com/html/modPage.asp?ID=150
or if you have the money the tutorial from 3dbuzz.com
https://www.3dbuzz.com/vbforum/sv_info_mfc.php


with the first tutorial i started with maya myself about the second one i can only say that it's well recieved by the 3d community and has a review devoted to it in the magazine 3d world

Good luck
