I am unclear as to how long post apocalyptic event she is being reintroduced. If, as you indicate the community has returned to an agriculturally based society, there would seem to be some degree of stability, not overly chaotic as other parts of your premise states.

As to the equipment she is carrying. I see no significant advantage to her survival if as you state low-tech items (home, pots, etc.) are still available. Most of the items she is carrying will only provide temporary relief. For example her flashlight, if she uses it for 1 hour per night and it last say 30 days, how is that really providing for the rebuilding of society, which is a much more long term goal. Her EMT-Wildernesses status would only seem to provide only a minor advantage, since the community still seems to be fairly functional.

I must confess that I find the entire scenario to be somewhat contradictory and confusing.
