With the car level on a Qwik-Lift, and the spare removed, I can sit upright on the floor to do this job. If you aren't going to use the spare, you probably don't need to carry it around with you. 
I picked up a fluid transfer pump that screws onto my diff fluid bottle. If you aren't using a gallon off this stuff, you may not need it, but it made my life easier.

No i am not a points guy, and i had no idea how long the spare has been in place, also i do not intend on using it either (AAA). Initially when i had this brain storm of an idea to drain out the old and replace with new, i was under the impression it would a be simple extraction and refill, however i am discovering that i do not own an 8 pt. socket, and i must remove the spare if i don't. So i sprayed the spare tire hold down with PB blaster, and pray i dont strip the threads on anything. i will keep you posted either way.

I'm with Mike on this. Its easy once you figure which tool fits the plug the best and be able to turn it. Seems like it was a odd number open-end wrench, 19/32 ? Weird size.
Leave the spare / tub alone. Why make more work for yourself and creating a second job to do the first job?
I have to top-off mine every spring, due to a gasket seepage. I mix unequal parts of the two lubes on my workbench. This concoction is put into a clear, squeeze, (condiment) bottle found at food supply stores. Refilling diffy is easy. Then put a dab of thread-sealant on the plug.
No need to do figure 8s or any of that bs. Lube is already mixed and will be thoroughly mixed before you get out of your driveway. You're good to go.
