The little packet of grease is SPLINE GREASE to be used applied in a thin even film on the input shaft splines. empty the packet as evenly as possible on the input shaft and slide the clutch disc on it a few times and in a few orientations to evenly distribute, wipe off excess.

For the clutch fork, clean off the contact point where it pushes on the throwout bearing, where it pivots on the fulcrum and where the slave cylinder pushes on it. A dab of extreme pressure moly grease will do. It's basically the same thing as in the little packet, but you need that little packet for the splines, and the little packet is a thicker viscosity so it doesn't fly out into the clutch disc.
