Hey Man, welcome.

I would generally recomend what perfrcto said, hit f1 and have a look at the tutorials, Maya also has some built in videos that goes over the interface, and how to move around etc etc.

I would also see if you can get one of the basic maya books form a library (the Intoducing maya books pretty good) and then grab some of the free tutorials form here, and take it nice and slowly, dont rush it.

Cheers
