Per,
Yep, it sounds like the 3-4 slider hub (or "clutch hub" if you prefer) has
broken.
You have two options. An aftermarket replacement slider hub is $108. The
factory replacement, which comes as an assembly including a new slider, is
$186. Either of these options will fix the problem.
You can purchase the parts and do the work yourself, but I have to warn you
that there are some special tools involved. If you don't have these tools,
forget about rebuilding the trans yourself. The minimum cost for special
tools would be $108 for the star socket to remove the diff adjusters plus
$79 for an econo version of the pinion nut socket. This is assuming you are
not going to disassemble the pinion stack (not required if you are just
going to change the slider hub on the mainshaft).
Answers to your specific questions:

Yes, you will have to remove diff and the pinion shaft, but you won't have
to disassemble either of them.

You can just replace the damaged parts, although I would never do it this
way. I guess if you don't care how many miles you get out of the trans, then
it might be worth the gamble.

The only parts that "must" be replaced are the 3-4 slider hub and the
synchronizer rings (Brazilian synchronizer rings are $5.95 each, new factory
ones are $56.63 each, good used factory ones are $6.95 each). Other than
that, you would need a gasket set ($13.45). If you are going for the
ultimate cheap rebuild, don't bother with changing the seals.
NOTE: Once again, I would NEVER rebuild a trans this way, even if a customer
wanted me to. I am only providing this information because you asked.
For comparison, one of our properly rebuilt 4wd Syncro transaxles is $2095
exchange. This price includes a 2 year unlimited mileage warranty.
