If the MS is driving the coil directly, then yes - you'll need the coil driver. If the dizzy coil is logic-level, or has its own driver, then you don't.

You COULD, but wiring a processor pin directly to the great outdoors is a quick and sure way to buy another processor. I would suggest some sort of protective circuit, like this:
