Wheels upgrade

Ι have a Bianchi Nirone 7 Veloce (2009), my first road bike. I want an upgrade on the wheels (currently Ambrosio WS23). The use is strictly no competitive.
I’m thinking for Campagnolo Khamsin, in order to remain totally Italian. I don't want to wait for the 2011 models.
1) Are they any good (and basicaly better than the Ambrosio) ? Ι have read good reviews but users say that the freehub makes a lot of noise.
2) I have read that "A special lockring with 27x1 mm thread is needed to mount the Campagnolo 9/10/11-speed cassette!" What’s this? (I have Campagnolo Veloce UD 10 speed cassette)
Thanks.
