Bottom bracket clicking/creaking. How much to fix?

I noticed approx 100mi ago that I'd get a click from my BB as the left
crank passed through the 11-10 o'clock position. I didn't think too much
of it as I thought that the sound was actually my shoelaces hitting the
frame. (Most of my riding is done in very quiet conditions)

I was wrong, it's gotten a bit worse. Now it's more like a 2-3 clicks
close together, or a very small creak.

The bike is a late 90's Trek 6000. (don't remember the exact year I bought
it)

My questions. This is probably the BB, right?

I don't have the tools (or knowledge) to replace it myself, how cheaply can
I hope to get away with at LBS? (I only have one in reasonable driving
distance)

Assuming it is a BB, how long can I let this go before I do expensive
damage?

Thanks,
Mark
