Well, if you know for sure that you want to be in the unit I would put in the College Program app right away (if not accepted you can still do option two). Never hurts to give yourself a couple of shots at applying. If, on the other hand, you aren't completely positive you want to be part of the unit, then by all means go option one. Good idea to know what you're getting into.
Good luck with the apps.
