Don't knock your lists.. they're great! I tried to think of ways my Grand Cherokee might be disabled and how/if I could fix these issues on my own. In addition to your list, I've added:

1. Gas syphon: I bought the best one I could find (Pep Boys, I think). My grandfather told me if you get stranded someone might stop with their car all full of gas, but no way to give it to you. Made sense. I've always carried one of these.
2. Hose tape (I keep water in the car)
3. Small set of hose clamps
4. Spare fuses (mixed assortment)
5. Spare leash and high visibility collar w/name tag (we use the orange collar when he swims at the lake)
7. Spare large compressed bone (would also act as a meal for my dog... he'd just think he got to eat twinkies for dinner!)
8. Glass hammer w/seatbelt extractor (in glove box)
9. Blanket rolled up
10. Marine emergency strobe (it's really small and works great) as a signal at night
11. Radio Shack wind-up radio (great for not killing your car battery when you're just goofing off at the lake)
12. Tire repair kit (a good set where you can plug your own holes) from Pep Boys again.

In addition to the tire repair kit, I have the obligatory can of Fix-a-flat. I've been looking for a better way to refill a tire after a repair, but don't know if a small tire pump is something I can use on a car (Similar to a bike pump). Any suggestions? My tires are large!

I've also been considering putting something for radiator repair (I saw a tube of stuff you put in your radiator that "fixes leaks" for you)... but I don't know if it would work well or not. It looked like gold goop, if I remember correctly.
