BTW, as for learning to do all that. I assume somebody else with connections to the industry can answer you correctly (or perhaps look in the CG-society forum), but I am pretty sure there are very few people that make movies on their own(would love a few names if anybody know any) just as there are few people who makes games of their own(but there are people).

What I am saying if that if you are going to do it all yourself I guess you must expect to do them less detailed or expect it to take a veryyy long to finish even a short film. Look at the indiegames made by one man acts and compare them to big stuideo games and you can estimate how much simpler you must make your movies.

So go for it but don't expect do do Avatar kind of stuff
