Welcome Zero! Nice to see another Ohio member ( youngstown/warren area here ). For a supposed noob starting from Zero, you sure have a nice laid out plan of action. Looks like you already have done alot of research.
My 2 cents would be 1) I wouldnt worry about a weeks worth of "survival" clothes. My thoughts ( and Im a noob so I could be completely wrong ) are that if your buggin out space is gonna be at a premium for what you can carry/take. I would just make sure you have enough to layer for the weather/environment. And 2) Be careful when getting into firearms. Its very addicting and money consuming, lol.
