FIRST, do no harm. If you seek out decent training you will be able to answer your own questions. You can purchase stuff but not competence. In 24 years of working as a combat medic, paramedic and PA I used a tourniquet once outside of a warzone and never clamped an artery outside of surgery or an ER. Wound closure beyond steri strips can cause more harm than good if done w/out understanding the pitfalls. Sutures and staples work well when done after proper assessment and cleaning.
There is a tremendous amount of good info available and You Tube will give you a good start in visualizing what you need to know and practice.
Pro tip, a decent headlamp is essential.
