wrt the expander plug, do you mean below the top of the headset bearing?
Don't use a tubing cutter. Use a hacksaw with a fine blade and then finish off any rough edges with a file. You want the expander plug at the same height as the stem where it clamps onto the steerer. This makes it much less likely that over-tightening the stem will crush the steerer tube.
