I found that the Red Cross and http://72hours.org/build_kit.html provided good lists for building our kit. We tackled and water, food and batteries portion of the kit with a trip to Costco. In addition to a kit of freeze dried food to which you just add hot water, we are including items like canned tuna, beef jerky, dried fruit and peanut butter which don't require water. I also ordered a first aid kit from drugstore.com. After it arrives, I'll assess what other first aid items and medicines I will want to get from a local Walgreen's to supplement the kit.

It's recommended that you put the kit into a large waterproof container with wheels so that it's easy to move around. Mr. CP and I haven't yet decide the best for us to keep the kit together in a safe and convenient place.
We will also prepare a smaller kit to keep in the car, in case our larger emergency kit is somehow rendered inaccessible by a disaster or if we aren't near home. This one from REI is expensive, but looks pretty complete and self-contained, which would be good for keeping in the trunk with a few additional granola or energy bars.
