Nice list, Verg. Much of that is applicable to any natural disaster. Although it is really no laughing matter, some of your items gave me a chuckle. Common sense is really not so common, it seams.
I'd add that a small solar charger and rechargeable batteries are also a good idea. Far cheaper than a generator and you can get your cell phone charged up with one, provided there is any cell service. This one is well regarded.
Also, more than the next meal worth of food is an advantage when you don't know when the lights are going to come on again. Best to put this away well prior to any warnings. I live in earthquake country. We don't get warnings so I maintain a few weeks of food in the pantry as well as a week's worth of water and a few gallons of bleach for water treatment should that run out (I live close to a river so have a supply).
