I've seen several auctions on ebay over the last 8 months for power window and lock switches on ebay, even some NOS parts.
Beware the no-name door lock actuators on ebay, skip those and buy a set from NAPA or NOS Motorcraft if you can find them.
Speakers, In case you don't know... Crutchfield is a great place to find what fits your vehicle. They are a little more expensive then you can find at some other places, but they often include stuff like instructions and wiring harness and mounting parts for free.
