No idea what I'm doing

I'm a college freshman pursuing a BS in electrical engineering at UNLV. I've always been interested in orthopedic surgery or anesthesiology. My girlfriend is a critical care nurse here in Vegas, and thinks I should shoot for med school. But I have NO idea what I'm doing. The gist that I get is that as long as you have a great GPA and MCAT score, are personable during the interview, and get a few solid letters of recommendation, you've got a good shot. Am I on the right track? Also, I'm 32...
