When the clutch is brand new the tangs on the friction plates and the matching surface of the basket should be flat. Over time the friction plates batter the basket and form the notches you have seen. When they get really bad the plates can catch on them as you let the clutch out.
Ah, just re read your post and your talking about the half moon shapes in the driven plates!! Dunno if these should line up. It would seem obvious that they should but i have never bothered!!
I wouldnt attempt to re finish the surface, they should be very smooth from the friction plates - if you rough them up it will just eat the friction plates more quickly.
I have no idea what the damage on the ends of the fingers could be.
