Sounds like you may have a worn out bushing!
Do you push the clutch pedal really hard?
( It would account for the clicking and the adjustment problem) unless you've got over 60,000 miles of city use on the car.
You probably need to get a clutch quadrant adjuster, & some bushings for the pedals, and check to see that it's not bent.
If it is your clutch, swap out the flywheel to a light weight model while you have it open, that will make the MOST difference in the car's ability to accelerate, outside of new gears.
With gears, it's even better.
