I can't see the website but I'm assuming that it is the Shimano freewheel on Performance? If so, it would work with your chain. Respacing is easy, you need cone wrenches to loosen the nuts and you tighten the nuts one side or the other. Redishing could be a pain in the ass if you don't know how, I think Sheldon teaches you how to do it but might be hard to do...taking it to a shop might be a good idea.
