as far as rims, the openpro is definitely a better rim. it's sturdier and stays in true longer. however, i know a lot of people who ride ma-3's and like them. i'd pay the extra $10 per rim and go openpro though. it comes in black, too.

as far as black brakes, the 2003 shimano 105 comes in black finish. i believe you can get a pair for $50-$60 new.

as for the rest, i don't know... it's a process of looking around and see whan you can find within your budget. if you have the money you might want to buy a complete track component group, like jasonyates did. it would be nice to find a LBS that is willing to help you out with the search.
