I used heated grips and eel skin gauntlet gloves (aero stich). Plus a thin set of work gloves for tire changes. They weren't water proof, but we were lucky. Bark busters will help keep air off your hands, plus good ones will negate the need for extra levers.
I like to carry mixed nuts, for snaking on plus good energy just in case. Usually I had three freeze dried bags, 2 servings each. Plus only had a small pot for the stove, and a metal cup for hot chocolate/tea. There are concentrated drink mixes you can buy for a liquid sugar fix. You shouldn't need a lot of pots and pans, should be able to get by with a small one.
There are plenty of places to get food, so your not gonna starve! Unless you break down in Nevada....
I used a small a Butterfly chair, but prefered a camp rite three legged one. easy to pull out as use as a stool, or lean it up against the a tree.
