Help required to learn graphic design

Hi,

So, I want to learn how to do graphic design similar to the amazing models that are posted daily on this forum. However, I am not studying digital arts in school, I am studying computer science. I am interested in learning how to design with Maya. I got my free student license and I was wondering what manuals should I read in order to properly learn Maya. Also, I was thinking about buying a drawing tablet to use in Sketchbook. Any tips would be nice.

Please help.

I didn't find the right solution from the Internet.
