Yep. Always a good start.

Perfect. Though there are other ways this is the preferred approach.
As always, you /should/ stop the backend before running mythtv-setup,
even if you don't /have/ to.

If the storage group has the same name as before, there's nothing to
change in the database (other than the directory location in the storage
group, which you changed through mythtv-setup). Therefore, it's not
slower (nor is there any faster/more efficient/better performing approach).

That's true, but would only apply if the user were to move a file from a
directory in one storage group to a directory in another storage group
(and that's not in the first storage group).
