Final update (I hope) - after 100 miles, the left side boot indeed started leaking at the big clamp (flinging blobs of good grease around), and the small clamps continued to seep a bit of liquified grease.

Took the axles off the diff, disassembled the diff side CV joint, replaced the boot and clamps with the Subaru kit and used Redline CV-2 instead of the Subaru grease. I was lazy and did it on the car (without removing the axle nut and pulling the axle from the hub), but that was just fine and saved me the hassle of dealing with the axle nut.

I started from trying to drop the diff, but that didn't work out so well and started leaking diff fluid (as I couldn't keep the diff level). Bolted the diff back to the car and instead went from the hubs - two bolts removed and it was pretty easy taking the axles out of the diff.

The biggest struggle was actually getting the axles back into the diff. At first I hammered on the hub side (piece of wood on the axle nut), but that didn't do much. Then I hammered a large screwdriver on the small lip on the axle at the diff side and that went right in.
