New to Wedding Photography

[Jenwinphx]

I know this has been a topic before but I am doing a friend's wedding pictures this weekend and I would appreciate any tips anyone might be able to give. I have a Canon 10D and the wedding is at 3pm but we are doing "formal" pictures at 11am - what would be the best setting to have the camera on (Av, Tv, P)? Also I have a Tokina 19-35mm lens, a Canon 28-105mm, and a Canon 75-300mm w/image stabilizer. I am planning using the smaller zoom for group photos and then using the large zoom for the ceremony. I also have a 380EX speedlite and a Lumiquest softbox to cover it. Any suggestions???

Thank you!

Any suggestions Visit the locations at least a few days before the event & see what conditions are like. Take a few pics that include black & white cloth. Chimp. Shoot RAW.
Burn a few candles for St. Dismas, "Patron Saint of Thieves".
Pray! ;)
