Hi,
it’s not necessary for you to grease anything on the Throwout Bearing, it’s packed with all the grease it needs from the factory & sealed.Should outlive a properly installed clutch ass’y.
You’d meant the ” contacting the pressure plate’s fingers, not the Pilot bearing - correct?.-correct?
Only areas that require any lubricant is a skin thick dab of grease on the outside edge of the Transmission input shaft where it contacts to pilot, the ot hip better applied with a finger bearing (Should be pre-greased, if so you may leave it & the shaft as is).
The retainer shaft, which the TB rides on can get worn where the bearing normally rides & cause the bearing to contact the fingers at an angle, causing a noisy engagement, disengagement, finally a failed TB.
Only other surface(s) that lubrication helps is a very thin layer of never seize on the retainer that where the TB travels, a small amount on the splines once any nicks or burrs are addressed.
Another Common issue is people not running a Ford OEM Pilot bearing, run in all Ford T-5, T-45 Transmissions from the factory:

Or a FORD OEM Throwout bearing in the Clutch Install, nothing is better than OE at these HP/TQ levels:
Another issue overlooked is the bolted sleeve around the Transmission input shaft, (bearing retainer), and the operation of the TB, sometimes forks may bend under a binding clutch load is exerted, cable disconnected, run the Throwout bearing on the retainer where it sits & slides on, view the angle at which the fingers are being struck
If the angle is visibly off, or the TB wobbles during its cycling,.Check the below.
Tran Tb& motor mounts, all bolts (Bellhousing) starter, VV joints, get a barc& look for any loose, worn parts using leverage.
Does the car creep as I’d previously asked?
What type of clutch is installed, Oe bearings used?
How many miles on the clutch?
Adjust the clutch so the TB is contacting the fingers, about 1/16”-3/:32”. Run with a helper spring, if it works ok, I’d go with a firewall adjuster &!a quadrant if it isn’t working correctly..
Good luck!
