Tyres: depends what is "fast" for you. If you get a flat on the bike leg of a triathlon you'll lose more time than if you had used the slightly slower but more durable tyres. I like Conti GP 4000s (they are now replaced by the Attack / Force combo), they are sturdy and fast rolling (several tests showed this). Schwalbe is preparing a new tyre for 2013 that is supposedly as fast and maybe better. Additionally, tubeless technology is improving for road bikes, might be a good thing to check out. For tyres, also read:

Fast wheels: Zipp Firecrest 404 or 303 in the front and maybe a disk in the rear... but this can really depend on the frame! There was a test in Tour-Magazin (German cycling rag) two or three months ago, where they had that effect: another wheelset was much better in one frame than the Zipps.
Oh, and most of the high-end bearings cannot be repacked since they are "sealed" bearings, that is not cup and cone but rather a cartridge (note that sealed does not mean they are more waterproof than cup and cone bearings)
I recently found this article

could be interesting for you, too
For non-racing I would use something like:
- high-end Shimano cup-and-cone hubs (serviceable)
- Halo Mercury rim (reasonably fast + light + no carbon)
- DT double butted spokes (or maybe "aero" spokes), stainless steel
- laced cross three (reliable pattern), maybe radial in the front (not too much lateral load, not-measurably-decreased drag, almost no weight reduction.... but looks better?)
Now I need to go and find them... and tell my wife I bought bike stuff
again.
And it is your fault ;-)
