You will first need to tell if the problem is just in the pedal, or if it is in the transmission (i.e. fork).
An "easy" way to do this is to operate the pedal while not running and and feel for the bind, once it binds, climb under the dash and see if it has something to do with the pedal. (visually look at it while you move it up). The clutch fork is most likely the other culprit, but you should also check the slave cylinder is good, it operates like the brake system and needs fluid and bled properly. This is not an easy learning on thing to bleed. but if your fluid level is low, try adding some.
If the clutch fork is bent, I would assume it would make some noise, and or not release if the clutch is not spinning (car running). So if you listen at the bell housing while trying to release the clutch (again the car is not running, you will need a second person here) and get the clutch to release and listen for a clunk or a pop. Clutches make a little noise naturally, but you need to listen for something out of the ordinary. The clutch fork is right there as well, I don't think you could turn it by hand, but if you notice, the ram the pushed the fork, that could be binding too.. you would have to disassemble the thing so see if it is sticking.
Of course there is a strong possibility you will not find the issue if it is not running. But as a mechanic, I can't tell you a simple way to diagnose it while running with potential that someone can get run over.
