Hmmm.... I'm not sure how to interpret your post. I'm having a hard time picturing a crash that requires replacing BB, hubs and headset, so I'm leaning toward reading this as, "A lot of stuff got scratched up, so this seems like as good a time as any to trick it out." But then you mention that you'd like re-buildable and durable.
Re-buildable, as you have possibly just learned the hard way, pretty much rules out Shimano STI. You could go with SRAM Red or, if you really want to go bling, Campy (though there's something distinctly not right about Campy on a Macho Man, philosophically speaking -- even SRAM Red is a stretch). Another option which leads to "re-buildable and very durable" but doesn't use nearly as much of your available budget as you might like is Retroshift. Their stuff looks...uh...different, but it works great, is as close to bombproof as shifters get and is the only thing on the market that's actually designed with CX-like riding conditions in mind.
You choice of shifters will dictate what options you have for rear derailleur.
Crankset? I have a hard time getting excited about cranksets. The English bottom bracket on your bike keeps you out of the market for some of the really light stuff. If you go with SRAM shifters, a Red crankset would look nice with it.
