Andy,

Welcome to the fire!

That's a real nice setup you have. It seems pretty complete to me but I would add:
1. another 20 feet of paracord
2. AMK Heatsheet. With those you can rig up a nice emergency shelter in minutes.
3. a high-quality poncho might also be useful.
4. emergency cellphone charger (battery or crank)
5. maps of the area

I'd also spend some time scouting my area, both my work areas and the surroundings. Find out escape routes, sources of shelter, food & water, possible danger zones (steam pipes/dark alleys/wet cats/etc...)
