Looks great!
Some suggestions:
-get some duct tape (just a small roll is OK; you only need like 24 inches). I've heard those Asherman seals aren't phenomenal, and you may have to resort to a flutter valve type of bandage. Using the plastic wrapping and some tape, you can make an occlusive dressing for a chest wound. That silk tape you have should be OK, but you never know.
-Personally, I'd ditch the bite sticks. I've never used them as an EMT or a doc.
-maybe 1 or 2 oropharyngeal airways? These are "comfort" items though
-a couple packs of KY for the nasopharyngeal tubes.

See if you can bum around with a medic or corpsman for modifications.
