When I worked at sherwin williams we always recommended bin123 primer by zinnser(sp?) for the base coat then pretty much whatever you want to use on top of that should work though I'd recommend that whatever your topcoat is it should be a high gloss finish for ease of cleanups.
International makes a good tile paint. It's actually called tile paint.
Make sure your tiles are super clean. You will get the best finish by using a foam roller. Have fun!
