And now the computer will only boot via the GRUB loader. Which is fine with me (and it boots really quickly). But again it will only boot to 15.10, not to the two 16.04 kernels on there.

Do the two 16.04 kernels even show in the grub menu?
If not, it needs to be rebuilt. Try "sudo update-grub" in a terminal.

Anyway, for the sake of giving the 16.10 upgrade a better chance of succeeding, do you think I should change that
GRUB_DEFAULT=4
back to
GRUB_DEFAULT=0
?

What that does is change what OS selection is the default to boot into when the machine is started. It should not affect the success of an upgrade.

I had to Look Stuff Up. I know how to do that. You would be better off creating an account on the Ubuntu forums and asking your questions there. It's why they exist.
If I recall correctly, the 16.04 upgrade worked on your machine, but after it took longer than before for the expected screen to actually appear after booting. This is a video configuration issue, not a kernel problem. As I also recall, if you just waited a while, video
would occur, and your main issue was not wanting to wait?
I ran into something like this another Ubuntu installation. The machine used an ATI Mobility chipset, and would do 1280x768 native. After an upgrade, it would only do 1024x768 in Ubuntu. Poking around revealed Ubuntu knew 1280x768 was a supported video mode, but I never could find where to make the change so Ubuntu would do it. That actually did get fixed by another version upgrade.
