I shot with a D200 and my D3. I have also begun bringing another person with me to get more of the random people shots, while I'm getting the important shots. I always sit down with the bride and groom before hand to figure out what style they are wanting for their photos, journalistic or posed or a combo. Usually a bride has gone through so many wedding magazines that she has a few specific shots in mind. After getting to know what they want, I make a shoot list. Once I make sure I have everything on the shoot list I let my creative juices take over.
Depending on the length of the wedding and how much they have going on, 300 to 400 is more then enough. Just remember you still have to edit the photos and get them back to the customer in a timely manner. Shoot to make a good phhotgraph. Don't just shoot to shoot. Take a breath, take in the scene, and document the good stuff.
The woman came out of a man's rib. From the side to be equal. Under the arm to be protected, and next to the heart to be loved.
