In addition to what you've already collected, you will want the following. Not everything needs to be purchased immediately, but eventually you will use it all.
T-8 Torx (for portable computers)
Precision screwdrivers, phillips and flat (00, 0 phillips)
kapton tape
2x putty knife 2" (Mac Mini repairs, separating casings)
xacto knife
compressed air
static safe vacuum
grounding mat
good worklight
screw trays (Must have! Use egg cartons if you have nothing else, but a plastic screw tray that closes, in case you have to step away for a bit, is a lifesaver!)
multimeter
flashlight
Best of luck to you in your new endeavors.
