Update: If you can't get the parking brake cable off the caliper by squeezing the tabs with pliers, use a small hose clamp to squeeze them all. That's what I had to do when I did the other side of the car today. That side was so bad, however, that I didn't do the CarQuest procedure. I just removed the lever and put it on at the next position.
I fixed a leaking transmission coolant hose while I was under there. They can be a problem on auto trans Fieros -- If it comes off while you're driving, you have a real problem. I double-clamped it.
