For the tyres,I'd personally stick with the Maxxis CC's. Just as good, and cheaper. For spraying the frame, choose whatever coour you want. I made a topic before i sprayed my one, to get an idea on colours, and then I played about in photoshop to get the colour sorted. It's really not hard to spray frames, just get all the paint off (in your case stickers and lacquer?) and the primer it, then the coats of the paint of your choice, the lacquer. EDIT: For the bottom bracket, if your Square taper is fine, leave it.
