If i don't get into med-school right after school, will 2 years as an Air Force officer help?

I can't answer most of your questions, but I since you are interested in the Air Force, I wondered if you knew about the Uniformed Services University of the Health Sciences, in Bethesda, MD near the NIH. The GPA requirements are slightly lower than other US medical schools as are their median MCAT scores. When you started med school there, you would start as a 2nd Lt in the AF and get that level pay and benefits and you would pay no tuition. When you graduate, you'd be promoted to Captain. After your residency (which would probably be at a military hospital), you would have to work as an active duty medical officer in the Air Force for seven or more years.
