I also do nearly all of those, plus try to follow the suggestions in the body of the article following the five points. I'm changing out a lot of the lighting in the house as well, and substituting the energysaver bulbs in those as well as in existing fixtures as incandescent bulbs burn out.
I'm using low-wattage bulbs and have found that it takes a while for the 40W equivalents to become bright enough to see well in a dark room. (I've bought the enclosed squigglies for the ceiling fan, e.g. and they do take a long time.)
We also try to limit water usage, don't leave the tap running, e.g., and always turn the temperature to a low use setting at bedtime and when we leave the house.
The baggers at our local supermarket didn't know at first what to make of my collection of canvas bags. Now they give a 5-cent rebate for each one. I understand that in SF they've started charging people who don't bring their own bags.
