First off a disclaimer: I'm not a professional mechanic though my shade tree skills are reasonably good.
My recommendations are based upon ownership and clutch work on multiple manual transmission cars over the past 40+ years.
As a consequence, any "other than stock" adjustment that I discuss is performed at the owner's sole risk.
With that out of the way, I'll be glad to help in person if you're in the Austin area.
If not; remember that the "upper" or "released" pedal adjustment should require depressing the pedal about an inch before you feel resistance from the clutch master cylinder.
This assures that constant pressure isn't bringing the throwout bearing into contact with the clutch pressure plate.
As you learned, the throwout bearing soon wears out.
If you noticed discoloration on pressure plate diaphragm spring I hope that you replaced the pressure plate as well.
The "lower" or "depressed" pedal adjustment should require that you release the clutch pedal from the fully-depressed position at least an inch before it begins to engage.
This ensures that the clutch fully disengages during shifts and at stop lights. A dragging clutch wears the driven plate quickly and overheats the pressure plate.
It can also lead to "crunchy shifts" and rapid synchro wear since the transmission is still being driven during shifts.
I used the "pull the pin and rotate the fork" method for my adjustment.
On my car, 1-1/2 turns from stock was the compromise that gave me appropriate clearance at each end of the travel.
Your car may be different after the transmission R&R to replace the throwout bearing.
PM me if you live in Austin and would like my help.
Either way, best of luck with the renewed throwout bearing.
