You can buy all the power window stuff on ebay. Get the wiring diagram out of the service manual. That will tell you what you need. I've bought enough for almost two cars. Usually you have to buy in bits and pieces, but over time you can acquire everything you need.
Here's what you need from an original set up for power windows:
1. Orange wire to fuse box
2. Relay
3. Wire harness to console switch
4. console switch plus retainer
5. door boot with harness to window regulator (one for each side)
6. harness that connects from the switch harness to the passenger side boot regulator harness
7. Regulators
I may have forgotten something...
Power lock stuff is also available on ebay. You need two lock solenoids, two power lock switches. The harness that connects to the switches and solenoids, and the harness that ties the two sides together. The power source is the same one for the power windows.
