Good work Garry, and at least you you now know the history of the clutch internals....and I agree, that cone will do the job and the fact that it protrudes does not indicate a worn clutch cork, as I suspected.
Re: the thrust bearing, from some research, they don't seem to be greased, however, I did push some grease through the small opening in my bearing with my thumb...and it definitely runs quieter and smoother.
