Thanks for the help guys. I think I'll just hold on to them in case I need spares later
(I'm a pack rat like that) and just start a fresh with the new wheels.

I didn't realize I could buy individual spokes. I took the spokes I had down to my LBS so I could be sure of getting the right lengths, and they'd only order them for me by the box. Now that I'm more familiar with the process, I think I'll use those websites you pointed out. Cheers!
