This is all good advice....but the best I read was to try your best to keep it simple, and the tone light. Weddings can be fun and a big party atmosphere...they can also be strange, with lots of drama that has nothing to do with you, but can get in your way while you're trying to get the job done.
By all means, meet with your bride at least a couple of times to get an idea of the style she wants, and a list of VIPs. And ALWAYS scout out the location!!! You'll just feel more comfortable. Test ALL your equipment and carry back-ups for everything.
To keep it simple....if she has only vague notions of the wedding style or seems willing to leave it in your hands, if you take several portraits of her, of the groom, the parents, and get the expected group shots of wedding party and various family members....tossing in as many "candids" as you can....you will do well. Your soft focus filter will be your best friend for the portraits. If your wife can operate even a point and shoot, she could snag some candids in B&W....just a little extra to make your effort stand out. Don't forget to get a photo of the cake itself. They paid good money for it, so give it some soft light and shoot it. That's an image that also can help to "divide" the book between the ceremony and reception.
Visualize some kind of "final" shot to close your book with while you have bride and groom together. Strolling away from you down a sidewalk if it's nice outside, or seated on the altar steps informally is cute. My husband and I haven't done weddings for a few years now, cause of the total work/stress thing involved....but we always loved putting together the preview book. That's YOUR fun part!
Finally....get at least half the money up front, enough to cover your costs. Should they all get drunk and merry, they seem to *forget* they still owe us working stiffs. It's a drag to talk business with drunk people.
Congrats on the gig! Have fun with it!
