When engine started and clutch pedal fully depressed to floor,
get a "ticking/clicking sound". If I let up at least one inch, there
is no noise. Mostly goes away when engine warmed up. No
problems shifting, no noise when clutch is engaged, no grinding
when shifting. What could it be & what will I damage if continue
to drive? Started six weeks ago, not getting worse (or better).

At first, I was gonna say probably your throwout bearing, but that would cause a noise with the pedal even partially depressed. I don't know, maybe your pressure plate is coming apart?

Could be T/O bearing, but it is probably broken fingers on the PP...in other words, you probably need to replace your clutch.

Would say throw out bearing as well. How many miles are on the car--and has the clutch every been replaced, I had one go after 1500 miles --due to an import pressure plate that warped on me...

Miles are 93000. '87 GT, original clutch & original owner.
Always easy on clutch and no riding so hoped it would
last longer.

Well for my car, I have a quad 4 swap however, The pin/rod that pushes from the slave cylinder into the tranny was pushing to far and rubbing the internal pivoting arm against the pressure plate

I'm gonna say it's the input shaft bearing. There's a sleeve made onto the bearing that the throw out bearing slides on. That sleeve can break off and let the throw out bearing move around too much.

If it is the input shaft bearing, you'll need to split the transmission case to replace it. It's not hard to do, though. No transmission internals have to be tampered with. Rodney Dickman has free instructions for download.

Clutch, throwout bearing or input shaft bearing - you're gonna have to pull the tranny to do any of them, so you might as well replace the clutch / pressure plate and throwout bearing anyway. I'd only do the input shaft bearing if it's bad. It's the only thing that requires splitting the case.

That is a jolly good life for a clutch on a sports car. Well done

I would just put in a new clutch and be done with it.

Mechanic that usually works on the car says
"Debris from clutch coming apart is hitting pressure plate;
Replacement est is $975 plus $200 for resurfacing of
flywheel if it needs it". This would be the first Fiero
clutch he has replaced (always a scary thought).

I am going to agree with Formula88. I had the same problem and it was the input shaft bearing. I thought it was the clutch at first and changed it twice before I realized it wasnt the problem. Can you feel the pulses in the pedal or just the sound? I could feel it in my pedal when mine broke.

3.4 TDC SWAP COMPLETED...this is going to be a fun car

I have not felt the pulses, but it is a definite clicking noise.
Sort of like when you were a kid and put a playing card in the
wheel to click on the spokes. But it mostly or entirely goes
away in about one-half mile of driving. And only occurs when
pedal is fully depressed to floor or within one inch or so
from the floor.

Clearly it's the first one he's ever done - if it wasn't, he'd be asking for a lot more money...

Tempting to take him up on the offer - except that $200 flywheel resurface. You can buy a new AC-Delco flywheel for $95 at Rock Auto...
