1. Ar 5.56, with silencer.
4. extra clothes
5. The vehicle thing sounds good, but I'm going with one of those 6 wheel drive 2 1/2 ton trucks the army uses, most recent version.
6. Can't answer. Where I'm at, what I'm doing, and who I'm with would all potentially change my decision at the time.
Given my answer to #5, why am I limited to those 5 things?
As a side note, I've come to realize that having a hard, limited list, solid plans that are inflexible, and one scenario in mind will not be in your favor once something happens. Keeping options open, and being flexible is going to get the best results. (Meaning, you might live to finish out the week).
