54mm Hub Socket (a real one, not the hub socket with the teeth, I hate those things, they tear up the nuts).
Rear axle tool. If you can still find one.
I've used the multi tabbed Dana 60/70 socket well over a dozen times on several Toyota 4x4s without any issues. I understand how you can round the nuts but it's due to improper use, not the socket. This socket can also be used on the 80's REAR hub nut. These sockets are cheaper than buying two Toyota SSTs and can be found at any parts store.
Buy a Toyota wire diagram book if you plan to that kind of work. A multi-meter with guess work just is ameture and time consuming. -- Buy atleast a $20 soldering station and do it right, no damn crimp or splice connectors!!
Other than the typical 8, 10, 12, 14, 17, and 19mm sockets I have a 22, 24, and 30mm.
You can kill two birds with one stone if you buy an impact socket set, they dub as deep sockets (of course if you have an impact wrench/compressor)
One set of sockets in 3/8 drive will cover up to 19mm but invest in a set of 1/2 drive along with both size drive torque wrenches
(I bearly use my 1/4 drive stuff but it's nice to have)
x2 that ratcheting wrenching are great things to have. a set of wrenches from 8mm to 19mm should be fine.
A good set of pliers including, needle nose, dikes, and in the smaller version
If you can, buy the proper phillips head driver set:

Hammers, rubber and a 5lb steel - no wimpy nail drivers needed
Brass and Steel drifts
3ft breaker bar
Snap ring pliers
Other tid bits:
Silicone grease in a tube
Lock tight
Black weather striping glue (great all purpose use)
Penetrating oil
A good floor jack with large saddle, no wal-mart junk with a dinky 3" saddle
12 Ton high rise jack stands x4
I've never felt the need to purchase a seal puller or driver. Some improvising and neither is needed but could save some time.
