I'm still trying to figure out why somebody is asking a question about shooting a wedding in the "Photography Beginners Forum"...
Wedding photography is NOT something that beginners should be contemplating at ALL... unless you want to shoot some candids at a wedding where a professional is being paid to shoot the ceremony.
To the original poster... I am not trying to be a dick here, but frankly you just don't have the equipment to do what you need to do, so you either need to find a way to get that equipment (and stone cold KNOW how to use it) plus a full and professional set of backup equipment in case your main stuff fails, or you should not do weddings.
Your equipment list does not include one single piece of professional grade equipment (with the arguable exception of the Tokina 80-200 f/2.8) and I see no mention of your backup equipment. To shoot weddings in a reasonable, professional manner, you need backups of EVERYTHING, cameras, lenses (or at least a big enough stable of fast lenses so that you can work around a failure), flashes, memory cards, batteries, EVERYTHING.
I don't shoot them any more, but when was in the wedding photography BUSINESS I had a duplicate of EVERYTHING... and three of the stuff most likely to break. My wife was my assistant and we would event take two cars in case one of us had car trouble, we could just park the offending vehicle and continue on the the ceremony.
Wedding photography, at least to do it right, takes a commitment to have the equipment in quality and quantity to do the job right... and years of experience with all the types of lighting situations that you will encounter... not a bare minimum "get you by" equipment list and not nearly enough experience to nail it every time.
BOTTOM LINE: you have to nail it every single times with weddings. Every time.
I gotta be kind of frank here... if you have to ask how to handle a lighting situation like you describe, you shouldn't be shooting it for a one-time-only event in the first place.
