Best way to prep rallye wheels for paint?

Hey guys I just acquired a full set of wheels that need some help. There are tires on them and I can't afford to sand blast them. I just wanted to put a decent factory colorish rattle can paint job on them. I was wondering what the best at home method on the cheap to remove the paint and rust would be? Should I use a wire wheel, aircraft paint remover, good ol sand paper or what? Also whats the closest paint match for a factory finish that can be purchased locally in a can? Thanks in advance guys.
