I don't recall if it is Lennard Zinn at www.velonews.com or Uncle Al at www.roadbikerider.com, but one of them has an entire section on cross compatibility between Campy and Shimano gear. Go to either site and search and you will be rewarded. It is quite extensive and should answer all of your questions. If not, then both LZ and U.Al are very good at getting back to folks who send them e-mail questions.
Sheldon Brown offeres a mixxed set he calls shimanaglo.
