Well, you don't "really need to go with a Campy groupo because its Italian like the frame" BECAUSE that kind of statement indirectly infers that all those Asian fabricated frames should have Asian sourced components & hence SHIMANO would be the preferred component group (okay, FULCRUM components are apparently manufactured in Asia, too ...).
Having said that, I agree that you should focus your choice on Campagnolo components.
Are you getting the frameset without components? If you are getting the bike AS PICTURED, then I probably would only change the things which needed to be changed ...
If those are 9-speed shifters (nothing wrong with that, BTW), then I might consider upating to the "2009" 10-speed Centaur shifters + a 10-speed new cassette ...
Which components you choose would be based on your budget & aesthetic sensibilities based on your preference for alloy or carbon fiber.
BTW. Since the headset appears to be a Campagnolo Chorus headset, I'm going to presume that the rest of the components are also Chorus -- is that right OR is the frameset basically bare?
Since I, personally, don't feel a need to match all the components, I would only change the crank if the length is different from what you prefer to use.
