Gap Year, wondering about my credentials

I recently wrote my MCAT and received a 508 (129/124/125/130), but I am too late for this year's application cycle. I have a 4.00 cGPA and a 4.00 sGPA. I have done plenty of volunteering in countless places like the hospital, have made a club at school and started to gain some research that I can use for my application. Do I have a reasonable shot at applying to MD schools by any chance? What other things should I do to also beef up my EC to make them a lot stronger?
