Your Venge build shares some of the same parts as mine: http://weightweenies.starbike.com/forum/viewtopic.php?f=10&t=124146
You'll love the frame, it's super stiff and fast!
Cranks: Have you looked into either a Quarq or Power2Max for the S-Works cranks? Not sure about weights, but they both seems like feasible options to use the carbon crankset.
Chainrings: I have the Sram Red rings, but will get the Praxis ones when these wear out. They're 11 speed compatible and forged for strength.
Cables: I'm just running Jagwire Road Pro cables, but might switch to the Jagwire Elite cables over the winter in an effort to save some weight.
Brakes: The Sram Red Aero Links are pretty light and work great. I considered getting something lighter, but you'd have to spend a lot more to get only a little lighter than the Aero Links. I really love them and they definitely have better feel that the Sram Red Black brakes.
Bartape: I really like the Easton Microfiber that I'm currently using. It has a semi-gloss look and feel great. It also seems to wear well, as I have over a 1000 miles on them and they look almost new.
