Another vote for putting the 5700 groupset on the Norco. Looks like a nice bike. Another advantage of 10-speed (or anything relatively recent) is availability of parts. Its behind the curve a bit to not be too costly. But not too far back to be a PITA to get parts for it. Well, 9-speed parts should be easily available too (replaced an Ultegra 6500 rear derailleur earlier in the year). I have been wanting to replace the 6500 drivetrain with the Dura Ace 7800 stuff I bought used form a friend. Only missing parts are the brifters. And 7800 brifters are too pricey, IMO. Maybe could try the newer Tiagra or Ultrgra 10-speed brifters instead?
The Bianchi looks nice but seems a little too small. Would be a good investment to get a bigger frameset and move the parts over to it maybe? Probably not nigh priority since its a rain bike...
Edit: I see some Ultegra 6600 brifter on Ebay starting at $70:
