I bought all the tools necessary from iFixit except for the cleaning solutions for this step. You can just use isopropyl alcohol with a microfiber cloth to clean the thermal paste off before re-applying a new coat.
I found that the adhesive came up with the foam except for one screw. The adhesive just stuck to the head of the screw so I left it intact as much as possible and just pressed the foam back on. It doesn’t take much to keep them in place.
