I picked up a tip if you want to get the nut out of a fretboard - you put a screw-driver or other implement at the side of the nut (maybe with some cloth or something to protect the surface) and give the tool a good 'tap' (or two) with a hammer.
One good thing about music is that when it hits you, you feel no pain - Bob Marley
