In one of the recent issues of Modern Drummer there is a good piece on re-covering drums.
After removing and sanding the shells you can repaint.
For hardware and parts, there are a lot of places that sell stuff like kick spurs, like www.amdrumparts.com
The best place to inquire about drum repair would probably be www.drumsmith.com
and I think there is a site called Ghoste note, drum shed or something like that. That's pretty much all they do there is build and modify drums.
