I just posted a response under my old "bifold door" thread, but
thought it might be a good idea to cross-post under a better subject
line. I'm getting ready to redo/repair some tile around my bathtub.
The tub caulk needs to be redone, some of the tiles are loose, and
some of the grout is very discolored. I kinda know what I'm doing
with tile, and what the heck, I'll never get better if I don't try.
I'm thinking I'll use my Dremel with a grout saw attachment to get the
old grout out, but thought I'd ask if there's some other way you'd
recommend. Any other suggestions? Also (get ready for stupid
question), when I take out the old grout, will the tiles that aren't
loose stay attached to the wall? Or should I be prepared to redo them
as well as the already loose ones?

Any chance oyu could post some photos? Dirty / discolored grout can
be cleaned....often times easier than removing / replacing it.

Grout is the filler between the tiles, if the mud or thinset
(depending on the age of the installation) is sound the tiles will
stay in place.
Saw or grout rotary bit can be a bit hard to control, damaging the
tile is a risk.

Try to do as little removal as needed.

Dremel grout removal set has a guide which attaches to the tool - very
easy to guide. It has a tip that runs in the grout space.
