This is our plan, what do you think? Took apart the rear end. It's a 8" 2.80 ratio. Axel bearings are good and the pumpkin bearings seem good also. No gear damage or wear marks. I'm going to bring the pumpkin, axels and housing down to Ft. Worth Gear and Axel to have them clean it all in their tank. $25.00 is cheap compared to all the work we would have to do.
The person at the shop said that the tank would not hurt anything in the assembly, is this true????
I don't plan on putting any money, except for the brakes, into the rear end. We'll put it back on the car and look for a good 9 inch rear end to rebuilt and install, I figure the 8" rear end is good for another 1-2 years. I know the 2.80 ring and pinion gears aren't even available, and who would want them.
How does my plan sound? or am I on my way to a doofus award.

My son got me into this and I'm having a ball

The dipping shouldn't hurt anything. I had to put new heads on my boat last fall, the machine shop charge me $20 to dip the valve covers and rocker assemblies. I'm like you, it would've taken me an hour+ to clean them, and believe me, they wouldn't have been anywhere near this clean.

It's most likely they have a heated rotary cleaner that bathes the parts in a high temperature, high pressure solvent. this process is widely used in manufacturing, machine, and remanufacturing facilities and if it wasn't good the re-mfrg sector wouldn't use it. AS with any overhaul, just closely inspect the parts for any residual material that may have been overlooked, and feel the action of the components under hand rotation to see if you can find any grittiness. If so, just politely ask the guys at FWGA about it. If you have taken the front yoke off, make sure you put a new crush sleeve in as well as the new seal.

If your talking about having it dipped while still assembled, you'll have to re-pack all the bearings. I doubt you can do that without dissasembling it. At a minimum, squirt some gear dope into the bearings before you put it back together.
