Getting a non-resident tag is fairly easy. To add to Arcus Venator's comments, attachedis alink to the deer management unit map that shows if you need to take a doe before a buck...they are called Earn a buck units. There are also Herd Control Units which have additional antlerless unit hunts in October should you be looking for more opportunities for taking antlerless deer.
