Just to expand on what LukeD said, yes do organize your clips into the main events of the day. Get all the main headings and put all the clips that work (in focus, well lit, correct white balance) into bins. You could also do a little work on the narritive and do parallel action building up to when the bride arrives at the church or whereever. Have you got any video or film of the bride or groom (that's assuming it's a 'straight' wedding) as they were growing up.
