Is this screw on the face of the pickup itself, or is it one of the height adjusters?

You may not need to replace the pickup. Visit the service department of a couple of shops and have the techs look at it. It may be a simple fix, or you may find that you do need to replace the pup. Either way, you'll get a better answer than anyone here can give you, without actually examining your axe.
