Tom,
Narrowing the OLD may or may not require redishing. If you can get where you want to be by removing equal amounts of spacer from each side then you don't need to touch the wheel. If you need to remove more from one side due to chainline, room for the freewheel etc. then you will need to redish when you are done. From a practical perspective, if you redo the spacers and the wheel fits in the frame fine it is probably fine. If it is closer to one chain stay than the other then you need to redish.
