You need: fret wire, diamond fret file, fret leveler, fret hammer, edge rounding file, sandpaper of a few higher grits (320,400,600) some 0000 steel wool, fret tang nipper, some tape to mask the fret board, a fret bender of some sort (can be done by hand, but is tricky,) a fret remover. Then some glue either Titebond wood glue or some cyanoacrylate (superglue) That's about all I can think of right now, and it can be difficult at times, some fingerboards will chip when removing the frets and that will make another task of repairing those chips. All in all, it's not too hard to do, but it's not something you want to experiment on your own guitar right away, and it costs quite a bit of money to get all the fret tools, at least $400 or so.
