Go to radioshack and buy a soldering iron, some solder, and some de-soldering braid, then de-solder the joints that connect any of the wires on your pickup to anything inside the guitar that isn't the pickup itself (probably just the hot output and ground wires). Do that with both pickups, then buy the pickups you like, check out the wiring diagrams at www.seymourduncan.com, and solder the wires where they should go depending on what controls you want.

Hope that helps at least a little. I'd be glad to help you out more if you need me to go over anything in more detail.
