I'm a newbie to graphic design and I need help.

[Duma]

So basically, I recently got EXTREMELY interested in 3D modeling/graphic design; however, I have NO CLUE where to start developing my skills. Anyways, I'd like to know how to make something like this rotating sphere and audio spectrum: A grunge sphere rotating for almost 5 minutes. Please suggest any tools that would be necessary as money is not a problem for me.
Best, Duma
EDIT: Here's another example: A skull rotating around a sphere for almost 4 minutes. I want to learn how to make the lighting flicker as well as how to make the background move and morph. (Sorry if these are really simple questions, I really don't know what I'm doing)
