For fretting, I think:
Fret pullers, which can also be your fret end nippers
Fretting hammer, 8oz with plastic or nylon head is best
Long flat "bastard" file I thinks it's called, for leveling
Small file with edges ground smooth for taking the corners off the fret ends
Masking tape
Long level or staing egde
For dressing frets, I like to mask off the entire board, except for the frets, use a file with teeth on the faces only and re-shape the frets, then use 320grit sandpaper to remove the file marks, then 600grit to remove the 320grit marks, then 0000 steel whool the polish the frets, so I'd say get some 320 and 600grit sandpaper, but that's just my method. I use the same file for filing the fret ends as dressing.
