It sounds like you've cut down your electric quite a bit. I think the next logical step would be to start looking at your gas usage. I don't know how bad your house is, but in January of last year, I used 660 kWh of electricity, and 5400 kWh of gas. Thats 8 times more energy in heating (water and forced air heat) than just the base electric load, and that was just one month. Even in the summer, my gas usage has always been higher than my electric usage when converted to kWh. IMO, this makes insulating properly waaaaaaay more important than lowering electric usage, the next runner up would be water heating. I'm planning on making an enclosed shower very soon to reduce shower hot water consumption similar to this:
