I have added storm windows to some of my windows. The original windows
are Andersen double pane glass. I have put 2 inch styrofoam between the
original windows and the storm windows. Would it be more effective to
remove the styrofoam and replace it with bubble wrap?

Depends on your goal. The foam is better insulation, but the bubble wrap
will let some light in. If the insulation is not properly installed, it is
of little value anyway.
