Drew, is this a 5 gallon batch? If so, you should consider making a starter. I haven't run the math on your recipe, but what comes in that vial is typically not enough yeast count and you will underpitch.
That doesn't mean that you will not make beer, it just means that you will likely have a slow ferment and the possibility of under attentuating.
Use this caluculator Mr Malty Pitching Rate Calculator
and search around to learn how to make a starter, it's really easy, but it takes a couple of days.
