If you have zero training, an Izzy, OALES, or H bandage will handle your needs pretty well. Maybe some Quick Clot Sport sponges. I would say that you don't need compressed gauze yet since you don't know how to pack a wound. Add in some nitrile gloves, and some duct tape, and you should be ok until you get some training. The first thing I would look for after you get the appropriate training is a TQ.
