Also you may want to consider:
A small folding saw to clear fallen limbs from the road
A MPI All Weather blanket as additional shelter or small tarp, also works as a signaling device
Cyalume light sticks ( I know Doug hates them and they don't do well in cold temperatures, but they couldn't hurt and are cheap)
First Aid kit, as mentioned
Lithium batteries for improved cold weather performance and shelf life
Snacks that travel well
Hand sanitizer/ body wipes

Just my thoughts.
