Campy triples are really great chainsets and work well with their derailleurs, the Racing T series. I'm using one from around 2000 with the matching long-cage rear mech and front changer, with a 7-speed friction shifter and a SRAM 9-speed chain. It's really slick.
Campy and Shimano shared the square drive shape, but the tapers are different, and won't in general fit right. You really should get a suitable Campy BB or Phil Woods to fit it correctly.
