Sorry.  I guess the UUID was too long for my eyeballs and I
stopped reading.

As for which program to use?  Yes, I was rather confused.

The man pages for the two programs were less than illuminating.
Grub-install says "install Grub to a device" and grub-setup says
"set up a device to boot using Grub."   This doesn't help much:
it's not obvious whether a setup is part of an install or something
that happens afterwards.

Perhaps you should add a "ALSO SEE" section onto the man page that
says "Grub-setup is normally run via grub-install."   And, then one
for grub-install saying "Grub install ???copies files and runs and 
grub-setup."

Anyhow, thanks for your quick, polite, and helpful answer.

grub falsely(?) says it cannot stat
