No, that's not related.

Don't worry, the naming depends on timing issues (which device was
detected first during boot).  For this reason Ubuntu sets up /etc/fstab
to use UUIDs and not device names.

That's good.  I'm sure the /dev/sda* names are left in the comments only
(lines starting with a '#' character), otherwise your system wouldn't
have booted.

No.

I'm sure there's a page on ubuntu.com explaining all this... probably
this one: https://help.ubuntu.com/community/UsingUUID
