Sounds to me like you are pretty well set. As far as cookware, an inexpensive cook kit will do. Mirro, GSI and others make small aluminum kits with a pot, lid that doubles as a skillet, and plates. Lexan utensils are stronger than cheap plastic, but either will work. A small folding knife, like a Swiss Army knife with a few tools on it will work. I'd also have an insulated cup, like one from REI, plus a water bottle of some type.

Look at the list of "ten essentials" which covers the basics such as a small first aid kit. Bring some Band-Aids and a couple of feet of tape in case your boots cause blisters.

You can use Pure Aqua or Aqua Mira tablets to purify water instead of a filter.

Not sure what to suggest about the boots. You may wind up taking them back if possible or wearing heavier socks.

Bearpaw lives in your area, I believe. He may have some ideas on clothes.
