I've had the same shifting problems that bo00on described. Every few weeks I fiddle with it a bit, to no avail. At this point I think there must be something odd about my frame geometry, or something. I am shocked that I don't hear more about Campy shifting problems. It makes me think that I am missing something. The count of replacement parts so far (Centaur, all new):

1 pair of shifters (crashed and broke the left so took the opportunity to replace)
1 derailleur (med cage. This seems to have helped, which is ironic considering that a longer cage length is supposed to make shifting less sharp. I've since taken the med cage body and put my short cage on it under the hypothesis that the spring in the short cage Centaur derailleur was weak.)
at least 3 cable and housing replacements
1 derailleur hanger
1 barrel adjuster
3 chains
2 cassettes

Today I've toyed with different housing lengths: cut a longer than standard housing for the rear loop, and shortened the front housing slightly because I had experimented with it being slightly longer than needed the last time I tried to put an end to these problems. I may have made things a bit better, but I can tell that the problems have not gone away. I mean, dialing in shifting is not rocket science. There should be a large margin for error.

The great part is that I had 2006 Campy Chorus shifters with the same parts before and my shifting was flawless. I switched for ergonomic reasons, but at this point I am considering switching back. I hate hate hate the vague shift feel on Centaur and below anyway. Maybe if you like friction shifting it would work for you.

Based on my experience I would say that if you go Campy then buy something better than Centaur for the shifting components. Also, have someone else do it so you can blame them when it doesn't work. I'm about to plunk down ~$200 on a Chorus derailleur of some vintage and see if that works (I think that 10 and 11 speed should work identically). It is too bad, because I really like the ergonomics of Campagnolo shifters
