A couple of recommendations.
Substitute coban (vet wrap) for some of those ace wraps. It's available at several locations including REI and is superior for most dressing applications.
Lots of folks get themselves onto trouble with tourniquets. In most cases, direct compression is superior to attempts at cutting blood supply. Handled improperly you can certainly do more damage with a tourniquet. And the sad reality is that if you sustain a large arterial injury and you are alone way out in the sticks, that is likely lethal anyway.
I also carry a skin stapler but that won't be easily available and requires a bit more training to use.
Lastly I also like the burn jelly REI sells as it is primarily Lidocaine and can act as an easily applied local anesthetic.
