You may want to check out Newgrounds for all manner of tutorials and the like, plus you can submit your work for the world to see. Though make sure it's of a high standard, otherwise it will be deleted (or blammed as is the term round there). If you want to know what you're aiming for check out which of the lowest scoring movies get past the "under judgement" phase, and try being slightly better than them.

O and good luck.
