Well, I've been reading up on preparing a disaster kit for myself and I wanted to post it and get some suggestions.

I live by myself in Washington DC and do not have a car so leaving the area if something were to happen is probably not an option. My main worry is terrorism since I feel like I live in probably the largest target in the world. So, I tried to prepare a kit that would allow me to hunker down for 3 days or so without water or power.

My kit:
Various canned foods - I bought all items that do not need cooking/water
Can opener
4 gallons of bottled water
Maglite flashlight
AM/FM Radio
Batteries and spare batteries for radio and flashlight
Couple of cigarette lighters
scissors
AMA first aid kit with first aid manual (it has all of the items suggested on this website)
Pastic sheeting, duct tape and N95 masks (I realize that these are probably a little over the top the more I am reading about it, but they did not cost me much and I am going to carry one of the masks with me in my work bag as I use the subway a lot and live downtown)
Swiss army style knife
Soap
Bleach
toilet paper
Plastic bags (for various uses plus for waste if necessary)
I have enough clothes and blankets in the apartment for warmth

This is all I have right now. I was wondering about the wisdom of getting:
some sturdy gloves?
potassium iodine?
water purification items like tablets?

I also wanted to learn more about getting some basic survival skills and was wondering if you guys could recommend any basic, easy to use books.

Thanks a lot for your help
