The wire than runs from pup to guitar came out from the pickup, is the pickup ruined or is there anyway to fix this situation?
#2
What kind of pickup is it? Humbucker/singlecoil, covered/uncovered? Is it the ground or the hot? It's absolutely possible to fix some situations are just better than others.
#4
It's a single coil. both leads are disconnected. Do I just find two leads from the pup wire and solder them to the wire going to the switch? The pup has tape around the wire, but is otherwise uncovered.
