I converted a Bianchi San Jose last year pretty much exactly as the late Sheldon Brown did with his "San Jos8". It turned out really well for my 10 mile rt commute and the 8 speeds work perfectly for me. I have no experience with Chain Reaction, though. I bought the hub through Bikeman, wheels from Niagara and had a local bike shop build the hub into the wheel. The total was around $360 for two wheels, labor and the hub.
