how much material is removed? my shell is 68mm currently and there is a nick in the face.

Probably only as much as is needed to allow the bearing shell (or RH fixed cup, for taper BBs) to have something to sit on for it's whole circumference. If the nick isn't preventing the bearing from sitting square, don't worry about it - or if the nicks burred, just get the burr removed (or carefully remove it yourself).
