My 5 cents from someone who's bought 7 carbon wheel sets: get Sapim spokes (ideally, Xray) over Pillar. They cost a bit more but if you plan to actually use the bike, the difference is meant to be worth it. Better ride quality, lighter, less prone to mechanical failure.
The hubs probably matter less. Ceramic bearings are utterly unnecessary. I've had novatec hubs forever, they just work. You don't want hubs that need constant maintenance.
