Interestingly enough, I do have old windows, but I have interior storms. They are basically pieces of Pexiglass with a magnetic frame. A small magnteic frame is installed on the inside of the window, and the Plexiglass storms fit tight up against the original windows. I also have exterior storms, so even on the coldest days, you can put your hand against the Plexiglass and it isn't cold.

Doors are probably a good idea, but I don't like having no insulation on the walls. It actually makes the house drafty, and, in my living room where there is a lot of exterior surface wall, it can get pretty uncomfortable anytime the furnace isn't running (ie. after it has reached 70 degrees in the house). I've talked with people in Omaha, and they say that you get a huge benefit from instulating exterior walls in an old house.
