I would lube the throw out bearing sliding surface on the carrier and the pivot point with some hi pressure grease.
The bronze bushing will come in one of the boxes in the clutch set, it is installed int he end of the crankshaft and the input shaft of the trans rides on it.

I had mine turned it was in shitty greasy shape. Because of the tapered dowles pressrf in, it can be a pain in the ass.
if it is smooth to the touch with no visible discoloration and no steps int the face, i would leave it.
