Don,
  King of the spray cans here.
 First, I would recommend that unless you absolutely have no alternative, 
don't use spray cans. The paint looks good but as it cures, it shrinks 
somewhat and shows even the tiniest tool mark underneath. It also gets 
very brittle and unless you pay attention to it all the time, it will 
chip and flake.
 Believe me, I've done two cars this way.
 For prep, the minimum sander should be a palm sander. The drill 
attachment will leave swirls that will show up later as the paint cures.
 Rust treatment can be as simple as taking it down to the metal and 
priming and sealing. Heavy rust can be treated with comound such as 
Permatex Extend. Rust out is best resolved by panel replacement.
 Body fillers for dents etc. is a matter of choice. In this catagory, you 
get what you pay for. 
 My preferred method of fillers is fiberglass. It's harder to work but 
lasts forever if done correctly.
 You should use a sandable primer, which helps fill slight imperfections.
The color of primer depends on the finished color.
 I prefer red oxide primer for dark colors, and grey for light colors and 
metalic paints.
 Probably your best bet would be to do the body work and paint prep and 
pay for a paint job.
 There are shops that can give you a pretty decent acrylic enamel paint 
job for around $300. and gaurantee it.
 Give it lots of thought. Spray can paint is a lot more work than it 
sounds like.
Good luck in whatever you decide.
Best Regards,
Tony R.
