Okay, I checked and neither look like that. With that being said, how much of a pain in the ass is it to change the hub out. Should I attempt it myself or should I take it to the shop to be done. I have repair manuals etc.. but I certainly don't want to screw anything up. Also, how hard is it to transfer the cassette?
Actually, your cables are too short. They stop at the brake bosses right now. They need to go all the way to the dropouts.
Cables are relatively inexpensive. The wheel issue is a whole 'nuther animal. You can find a set of Specialized Stout hub/Deore hub with x317 rims fairly cheap on eBay b/c Specialized spec'd this on a gob of bikes and people are wanting to change to at least an XT level.
Search on eBay for them. They have been pretty reasonable and for someone with a tight budget, they should be okay.
Usually LBS's will charge for the hub, and then a nice hefty charge for labour(because they hate relacing wheels, it just takes so long). It might be a better idea to just upgrade your whole wheelset and get wheels with disc hubs.
