I am not a Toyota tech, but I do maintain some in our fleet at work.
Some common use items...
Body/trim clip tool or set.
Heavy duty mechanic gloves. The shop will probably provide disposable nitrile gloves.
Wide range 3/8 torque wrench. One that does 10/20/30 lbf for oil changes would be beneficial. I’m using a 10-100.
I used to just pull filter housings without draining but after a few nasty messes, I purchased the dedicated drain tool. It takes a little longer, but I’ll usually work on something else while its draining.
Plastic scraper. The Toyota OEM blue/black/silver drain plug washers will stick to the pan or bolt depending on which way they are turned. Prevents marring the pan surface.
Putty knife. To clear muck, grease, etc.
Wingless oil filter socket.
Threaded oil fill funnels. The shop may already provide these.
Double brake pad spreader for four piston calipers.
Wire brushes/bore brushes.
M8’s for pushing brake rotors off.
Slotted screwdriver to beat on and some high quality reasonable cost crosspoints like Vessel.
Pocket screwdriver, picks, air nozzle.
A locking extension helps with recessed fasteners in Toyota skid plates.
Any consumables the shop may not provide but could be beneficial. For instance, I use O-ring lube instead of just oil.
Grease gun for prop shafts if not provided.
Pliers. For general use I grab my 45° needle nose.
Magnetic parts tray.
