Get the 1 qt paint cups usually free, I can use a few if they are free. And a couple stir sticks, have plenty of industrial paper towels, a bit of masking paper not much, some reg masking tape, get green tape for the top, gives a good line. Have a few rubber gloves need to get more maybe 4 pairs of the blue ones.
I have yellow tape. Which is better the blue that I have been using. I may get some green anyway to do edges in jambs and stuff that I want clean line on already painted area.
