I shot a few weddings when I was young and would suggest that you need at least a good portait lense your wide angle should be ok for the large group shots. You will need a flash unit because it will get a workout. Its important that they tell you what they expect, for example you can't do video and stills at the same time - well. Also you won't enjoy the wedding because your 'working' and want to get it right.
Then you have the printing layout, album etc.
My best advice is to offer to pay for a professional to do a great job for them and enjoy it yourself.
