Sounds like you would be a best fit for rads/path.
which means you need to bust your ass for 80+ hours for the four years of med school with insane studying, research, and working long hours on rotations to get the best possible residency to earn your chance to to work in the rads room or path lab seeing no sweaty fatty mcfatties.
Remember, your grades don't matter if your ECs aren't tip top. As you know, you need HIGHLY strong ECs, and your GPA means nothing for the MCAT. Until you take a practice test, then you will know. As you already know, you need to spend countless hours to max out your MCAT as high as you can.
Plus, interviewing. You need to express to them a broad amount of interests/hobbies(no adcom gives a **** about videogames or sports), and go in depth on your long hours of research and clinical experience. It's not bad, but a lot of work
