I am shooting a wedding in 2 weeks, help wanted!!!

A childhood friend saw my images on Facebook and asked me if I would shoot her daughter's wedding on the 22nd of this month. I first told her no and explained to her a wedding photographer and an artistic/landscape photographer are two completely different animals. She insisted I do it, so I told her I would do it for free if there was another wedding photographer there and don't be mad if I don't come up with one good image. I told her I will do it for the practice.

So what are some good basic rules of wedding photography? It will not be at a church, it's at a reception hall (and ceremony maybe outside)
