>>2” x 2” sterile gauze pad
I´d add more of those

>>Ammonia smelling salt
>>Butterfly closure bandage
I´d ditch both items. The use of smelling salt is no longer allowed around here (I had to take them out of our unit´s first aid kits about ten years ago). Wound closure may not be a good idea for first aid.

>>Steel wire
I´d suggest to use stainless steel wire. It will not rust if it gets wet.

>>i was thinking a morse code key would be useful
If it´s a cheat sheet sheet it can´t hurt having it.

I´d suggest to add at least a pair of latex or vinyl gloves to prevent infection and keep your hands clean when dealing with bleeding wounds.
