Re: just sliding the old belt off, and a new belt on without
disconnecting/loosening everything:
Advancing a tooth - yes, replacing - no. You'll need to remove the
harmonic balancer.
That's not that big a deal, I now am to the point when I do a timing
belt on a 10v engine in under an hour.
Having a special locking tool helps, but on numerous occasions before
that I used a mid size pry bar jammed in the teeth of the flywheel
through the Hall sensor window (you'll need to remove the Hall sensor -
only two 5mm allens).

On the belts that I've seen, @ 50kmi the teeth are barely chamfered, but
@ $15 for a new belt I personally wouldn't even think twice. I'd replace
it at a _slightest_ suspicion. $2k in potential head damages just don't
justify saving $$ on the new belt.
Perhaps yours was overtightened? You know, that "calibrated thumb"
method....
I usually keep mine just a hair on the loose side (as well as the P/S
pump belt).
