I'll have to replace the chain so I can make sure to get the appropriate one after I sort this out.
Errr, don't go too fast, or you might end up buying stuff that you don't need, or that doesn't work.
When you say 'tire,' I'm assuming that you mean wheel. And assuming that your wheels are the same size on both bikes, you can probably move the tires around easily (as long as they fit in the frame).
Cassette compatibility is another story, and as mentioned you generally want to get the right chain for the number of gears you are running. New chains can be pretty cheap, and that will also guarantee that you can set it to the correct length.
