EMT training is nice when you find yourself in clinical environments, because you hopefully know a bit about what you are doing, and it looks good as an add-on to your application package... but don't count on that alone to get you into medical school. I basically feel that EMT training (and especially EMT experience) is an excellent ancillary activity to your studies. We have about 4 or 5 EMTs in my medical school class of ~120.
Good luck!
