Will this re-compress an already-compressed GIF and lose quality?

Yes, to an extent — that's true of any lossy re-encode. The Target File Size tool shows you the trade-off before committing, so you can decide if it's acceptable.

What's the fastest way to shrink a GIF a lot?

Resolution has the biggest effect on file size — try the "Smallest size" preset or the percent-based resize before fiddling with quality alone.
