I took DB's advice on the nuts. I used brushable superglue, put a swipe on the nut slot stick the nut on and hold for a few minutes.
Don't be worried about only putting a few dots of glue on as mine still come off with a little wack fron the fret leveling bar.
The bigest issue I have had with putting my nuts in the right place is getting the slot to line up properly after I have trimmed all the old furry bits off with the file.
