OEM Clutch, Flywheel, Pressure Plate

So I have a set of one clutch disc, pressure plate and flywheel from my 2015 Tacoma v6 4x4, manual transmission. At about 17000 miles the clutch started slipping slightly when on 5th or 6th gear and giving it good gas. I thought it was worn out so i bought a stage 3 and new flywheel to replace it with. When I picked the truck back up from my mechanic he said the clutch was still in great shape and the problem was in the throwout bearing. Apparently the shaft on which it rides is aluminum and the bearing was starting to chew on it. This didn't let it put enough pressure on the plate and the clutch was slipping a bit. He was very pleased with the URD sleeve for the bearing that goes between the bearing and the shaft to prevent this problem. Anyways, these are the prices I have in mind:
-Disc - $70
-Pressure Plate - $90
-Flywheel - $250

If interested message me and we'll go from there.
