Good luck,
Sounds like guite a job. I guess the spackler will follow up with whatever damage you make. I've heard stories where the carpenters will open the sheetrock up from the floor 1 1/2', so that the wiring can be drilled in, and then the rock is repaired after. It's almost the same as new construction then, along with alot of fishin. It's great if you have a carpenter that will work with you, or the homeowner, in the case of a complete re-wire.
