Two things in particular were a problem in the big ice storm a few years back: heat and food. I had friends I was able to crash with on several nights, which made a big difference. I'm still thinking about some kind of indoor-safe propane or other heater(not worried about being toasty, just a bit more comfortable). I've also got the Aladdin oil lamp I picked up last year; if you've never used one, they produce about as much light as a 60-watt electric light and a fair amount of heat. You can burn kerosene in them, but for indoor use you're better off getting lamp oil: little or no smell. Yeah, the stuff costs a lot more.
Damn, I was just thinking of getting a spare mantle, and they're sold out; apparently a lot of people bought them recently.
Be aware, a lot of the oil lamps that have a wide, flat wick are good for some light, and a little heat, but not something you'd want to do work by if you could avoid it.
The heat part of cooking I was ok on last time, I used the two-burner unit I use for bluing and melting lead(yes, I cleaned it off VERY thoroughly). It hooks up to the same propane tank the grill uses, so I just made sure I had a full tank before the weather hit(I've got two). It was the food part, as in 'can't open and close the fridge or freezer or it'll let all the cold out'. So what I did was pick out some stuff that'd be easy to cook and give lots of calories; then the day before the storm hit I got a couple of bags of ice, and when the storm started put the selected stuff in the ice chest with the ice. I figured that if the power was off for long, I could use that stuff and not worry about the fridge/freezer. Experience shows that in this weather, the freezer will keep everything solid for a good three days before you have to start worrying about it, the refrigerator not quite as long. So if it was off more than three days I know where to get dry ice; unplug or turn off the unit, then put the chunk on the top shelf, if you leave the door closed that's good for another three days in my freezer, about the same in the refrigerator(chunk in the freezer compartment).
Yes, I've got non-cook food around, it's just kind of encouraging to be able to turn out something hot when it's so cold and dark.
I do need to plan out my bugout supplies better; BRMs posts give me some good ideas there. I've never been in a situation where I needed that, but this is tornado country; if need be having some stuff ready to go in case the house/neighborhood gets hit would be a very good idea. For some reason I hadn't put any clothes in; a really dumb oversight.
