Here is my thoughts on "must have" tools for a simple disassembly and reassembly for freshen-up, not an overhaul with bushings, etc.

0. Something to pull the front pump. Slide hammer, chain, etc.
1. Feeler gauges for setting the clutch pack clearance.
2. Dial indicator to measure the input shaft endplay before and after.
3. Snap ring pliers to take the output shaft snap ring off/on.
4. Expander pliers to open the tail housing bearing retaining ring to get the tail housing off. But a couple screw drivers can get it done.
5. Front clutch compressor to change the seals (and maybe the springs). A home made one gets the job done (pic).
