To cover the basics I would want:

1) A good fixed blade knife (for me my Benchmade Griptilian)
2) Ferro rod
3) Small metal container (for boiling water)
4) Para cord (the real stuff of course)
5) A small tarp

I chose the ferro rod because, in my opinion, it is the most reliable way of generating sparks to create a fire. Recently as an experiment, I have started dry grass, cat tail fluff, cotton balls, and shredded paper towels on fire with minimal effort.
