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?

Sealing or weather stripping the storm windows would probably help. Neither bubble wrap or rigid insulation seal to the surrounding frame.

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.
Fill the space with great stuff. It's better than styrofoam or dead air.

If the intent is to eliminate the window (i.e. block out light and view) and to increase the R value to the max, why not just remove the window and frame it in, including fiberglass insulation.
