Cindy, I confess that your post leaves me breathless with your enthusiasm ... and the amount of work involved.
Although I am always intrigued by the notion of "rebuilding civilization after the apocalypse," in practice it's more than most humans can achieve on their own.
The John Ford "Wagons-Ho!" narrative is a lovely fiction. Humans thrive and survive as communities, farms and villages bound together, and have done so long before written history.
So, in answer to your question, I would add as a vitally essential skill: "The ability to build and foster community, a sense of common cause, support in the face of disaster, and honest trade in skills and goods, for the common good."
