Empowertorch, got all that stuff, including the 5 gallons of gas. (Make sure you use and replenish the gas within six months since the stuff goes bad without adding preservative) Its a good idea to have a means of living without leaving your house for a couple weeks no matter what the international situation is. Life happens. Here in Michigan for instance we have to worry about freak snowfalls, tornados and floods. In other areas of our country they face potential earthquakes, hurricanes, and an assortment of Mother Nature's other tantrums. Heck, just a few weeks ago it got so cold that pipes to our area froze. It was water that I had on hand that made getting off to work and school shaved, brushed, and coffee'd much more pleasant.
The food part is easy, lots of cans of stuff you won't mind eating raw if you have to. No stuff that requires water to make (like macaroni) since you need your water. Throw in vitamins to stave off scurvy and other deficiencies during your emergency. Also have a supply of your favorite medicine. Besides necessary prescriptions, stuff like Childrens Motrin will be worth gold to homebound parents of a feverish child.
I have a wind up radio for incoming communications, been meaning to replace it with a shortwave capable model. Lighting is covered by a D-batt powered Lightwave 4000 and fluorescent tube lantern with a stockpile of 20 batts allowing a change of each twice, an oil lamp with oil supply, and assorted candles. You can pick up the unscented three wick blocks pretty cheap if you look and the light they give is more than sufficient. Water is stored in used milk jugs as they become available.
I have wood stored for about a week of fire, obviously if we need it we'll be living bundled up in the living room since its insufficient to heat the house. You need to plan for a means of using the toilet. Without water, no flushing. A ditch behind my house provides us with flushing water in a pinch, but lacking that you might want to consider a portable toilet or other means. Unpleasant but a necessity if you are going to be penned up with no water for any length of time. After you take care of the important stuff look for ways of making yourself more comfortable: battery operated alarm clock, board games etc.
These are just common sense preperations I've taken. Other folks have it down to a science and there's always other techniques and refinement of your own.
