Lot of good topics are covered there Hydrix13!
I would pay particular attention to topics about maneuvering injured patients, and dealing with wounds (recognizing types of bleeding and dealing with it etc) also important topic would be prolonged care for wound (for example if medical facility is not available for weeks or not there at all).

Proper bandaging-splinting injured limb can save you lot of pain, and lot of (dangerous complications.
In real life for non medical personnel use of steri strips would be more “possible” then stitches, of course that does not mean that you do not have to learn how to do stitches.
