OK, so you want better lists. You've come to the right place. Try
Doug Ritter's lists as a place to start

kits FEMA disaster library This is an interesting piece on urban survival.
Searching the forum for BOB or bug-out-bag or Bug-in or home kit or 72hr kit will turn up a wealth of information - be sure to expand the time frame of your search, by default it will only search the last weeks posts. The drop-down control at the bottom of the search page will allow you to select searching all posts.
The general priorities are:
water (1 gallon or more per person per day)
shelter (keep dry)
food (something more than 1200 calories per day - usually more than 2400 would be good)
sanitation ( burn it or burry it and don't eat with dirty hands)
first-aid (depends upon you level of training - get trained)
These priorities will be met differrently in different situations and in some scenarios the priorities will be re-arranged. For example in an earthquake situation the first-aid might come first and in a blizzard scenario at home you might want to add fire / heat. Always consider the storage and wieght of items as well as cost. It won't help to but a 300 gallon cistern in the attic if it falls through the cieling and distroys the house while you are filling it.
If you live down-wind of an industrial complex it is pretty important to consider the hazmat situations - terrorist have no corner on toxic chemical releases. If you live near a major trucking route or rail line you are at risk for just about every haxmat situation possible. Most hazmat situations are a matter of information and knowledge. If you are informed on what has been spilled (listen to radio - preferrably HAM or emergency scanner) and know what can and should be done you will stay and go appropriately.
stay upwind and uphill is a good rule of thumb. If your house is down-wind or downhill then you should have evacuation options well planned.
What I have
15 gallons of water
lots of canned goods
enough tarps to cover my house if the roof is damaged
extra blankets
some strong rope
a bunch of zip ties
6' pry bar and a bunch of scrap lumber with nails and hammer
bolt cutters;
charcoal gril,
white-gas coleman stove
Full camping gear == BOB +++
4X4 (Jeep cherokee) with BOB in back
Duct Tape everywhere ( I have a full 100 ft in each vehicle and probably 3 more rolls about the house - I have believed in this stuff for awhile)
Strong wire coat-hangers (near as useful as ducttape)
PSK
FAK
EMT Jump kit
Leatherman always on belt (except on flights and interviews)
Basically I started with doug's kits and embellished.
I have tried to think, If ( name the scenario ) happened and I was (walking down the street; at work; at home; in my car;) how would I take care of the essentials
water,
shelter
food
sanitation
first-aid
build it up in layers and you will always have some redundancy. For example, I packed a PSK and a FAK in altoids tins and they ride in my front pants pockets perfectly balanced. I also carry some readily accessible cord, a leatherman, a mini-bic lighter and some matches and a set of brunten survival cards in my wallet and a cell phone. This before I put on my Filson cruiser vest fully loaded with space blanket, balaclava, tarp, poncho, PDA, notepad and pen, flashlight, deck of cards, book (currently the teachings of the buddah before that "As a man thinketh") , spring loaded center-punch, match safe, whistle, mirror, bandanna, extra duffle bag, ear-plugs and eye-shades, Then I get into my cherokee with 2 gallons of water in the back along with a tent, and fully loaded 3 day backpack, automotive tool kit with jumper cables, motor oil, hand winch, duct-tape, camlock tie-down straps, tow strap, ratchet set, screw drivers, repair manual, muffler tape, coat-hangers, Transmission oil, radiator sealant, fix-a--flat, flares, emergency triangle, bright pink surveyors tape, transmission sealant, wd40, starter fluid, and ammo can full of canned food. - cheaper than MRE's though less complete nutritionally, Three band Ham handheld radio with amp and mag-mounted antenna, roll of trash-bags and roll of paper-towls and 5-10 mechanics rags, I drive to work where I always have a belly-bag stashed with trash-bag gloves, balaclava, GORP, Esbit stove, magnesium lighter, bic butane lighter, match safe, goggles, dust mask, Hank of paracord, compass, whistle, jackknife, monocular, Spare Cell phone battery adapter that takes alkaline AA cells and spare Ham radio battery adapter that takes alkaline AA cells. When at home I have all of this and above as well as similar setups for my two duaghters and my wife. Though they carry purses / sholder bags / backpacks. rather than wear filson cruiser vests.
I personally don't have any firearms and haven't missed them yet. I grew up in an inner city slum and moved out to somewhat rural New Hampshire but in all my life I haven't yet been in a situation that would have been made safer by my being armed. I am actively learning to shoot now and will be arming when I have enough experience to know what works for me. I don't think that protecting myself with a firearm is a high probablity event but I have started preparing for a lot of things lately and that is one of the events that I no longer can ignore.
Sorry about the length of the post but I got going. I probably missed some things since it came out as stream of consciousness rambling. Next time I inventory I might actually make up lists and post them.
