While obviously you are planning to boil your water to purify it, I would consider adding a Katadyn Hiker Pro Water Filter or equivalent for those times that building a fire just doesn't make sense. Also keep in mind you can fill a 3 liter Camelbak in about three minutes with one of these, whereas boiling that much water would take quite some time.

With regard to water collection in urban environments, I keep a 4 Way Faucet Wrench in my BoB. Most commercial/industrial water silcocks do not have handles on them (for obvious security reasons) so one of these wrenches will allow you to easily fill up the Cammelbak as you are heading out of town.

I don't see any cookwear listed - I would think that cooking game in nothing more than a Crusader cup or a pointed stick would get old pretty fast.

The final thing that I would suggest is either a good quality wrist rocket (I have a Crosman Tempest that I'm pleased with) or at least a slingshot replacement band that can be used to fashion one from a forked branch and some paracord. This might serve as a practical alternative to using up your ammo on birds and small mammals, and could obviously also be used to make a crude harpoon for shallow water fishing.
