A C- is not a death sentence for your application. I am a fourth year at NSUCOM (nova). I had three C's... one in zoology, one in orgo II, and one in orgo II lab. Man i hated organic chemistry. Anyways, just apply to as many schools as you can at this point, don't cross them off your list so early because of what you think they want on your application. The sources here on this website are good, but you have to remember that when it comes to admissions committees, no one really knows what they are thinking. I know people at NSUCOM that graduated college with an 18 on their MCAT.
If you posed the question "I got an 18 on my MCAT," most of the responses would be "take it again, wait a year, etc..." I would tell you just to apply, because schools really do look at everything else.
The MBS year at NSUCOM... several of my friends did it. And there are no guarantees. The deal is if you score 80% or higher on your grades, you are guaranteed an interview at NSUCOM, not a spot as a medical student. Beware. But if I were to choose between no medical degree ever, or taking an extra year to do that, I would choose that (assuming I do not want to become a software designer).
