I would add a blastmatch and as many of the individual wetfire cubes as can be conveniently be carried. And you cannot have too many butane lighters. I would also suggest that you go to the links page and have a look at the U.S. Rescue site. Not sure I agree with them about wire saws or knives but it's still a damned interesting site. Also look at Doug's comments about survival kits on the main site.
