Yes, thingstodo, and I actually use 0-65535 for the "degrees" so that when it rolls over, it automatically goes back to zero, so you don't have to worry about it.
mfox: I would use either a high side IGBT with a diode on the low side (I think they call those choppers), or an IGBT half bridge, since you need a freewheel diode too, and just just the IGBT. So, the part you listed wouldn't work for that.
