You're in deep now. I would assume your old rear wheel probably has a freewheel and not a cassette, 10 speed wouldn't fit anyways. I'd say go to velomine.com and pick up a set of open pro wheels with 105 hubs for about $200. As for the crankset, it might, you'll have to try it. I wouldn't be surprised if the teeth of your current chainrings didn't fit well in a 10 speed chain.
