I guess you should have said that from the beginning too. So, you have a vintage Bianchi and want to upgrade to 8/9/10 sp. It's easier to just buy a donor bike and strip off it's group & wheels. It will cost less than buying the pieces off of CL or ebay IMO.
A few things to remember:
1. The Bianchi may have Italian threading, at least the BB. The Ofmega crank seems a dead give away to that fact.
2. Your current wheels may not be English threaded either. You don't want to screw up the threads on the hub by trying to thread an English threaded freewheel on it. There are 8 sp freewheels available. IMO, anything bigger than 7 sp needs to be a cassette. That means a new rear hub.
3. Your bike is probably spaced 126mm. It isn't hard to cold set if you've done it before.
If you've never done a complete build before, a vintage Bianchi isn't the kind of bike I'd experiment on. Better to A. keep it as is and enjoy it. They were great bikes out of the box. Or B. sell it to a collector and put the funds toward a new bike you don't have to mess with. Good luck on whatever you do.
