I take it that you have no autochanger, just a standalone drive.

Bacula will not auto-label tapes. You'll have to do that manually.

Correct.

If you do not have an autochanger anyway, you could as well do away with
separate pools. Just create a single pool with all your tapes. The only
thing you'll lose is protection against accidentally overwriting a
monthly tape with a weekly backup, so your tape-changing "someone" needs
to be a little bit more careful.
If you want to get more fanciful, you can modify the retention periods
of the individual tapes with "update volume" so that your weekly and
monthly tapes have different retention even though they live in the same
pool. But I don't think that's worth the effort.
