For starters, you take a lot more gear than I do. I carry my camera, my flash, extra batteries (for the flash and the camera), extra CF cards, and I usually work with just a couple of lenses. I usually have my camera bag with me with my other lenses (rarely used, there as backups), and I may take my SB-28 along with my SU-4.

How many photo's I take depends on the wedding and the reception. My last wedding was a smaller wedding, they didn't do any toasts, they didn't have a DJ or a band, and they didn't do any dancing. I came away with a little over 350 shots. A larger wedding, larger families, band and/or DJ, toasts and dancing, and the picture count goes to around 500. That's for a typical four hour wedding. Subtract time and the picture count goes down a little (you shoot faster), add time and the picture count goes up a little (after a few drinks, the pictures aren't anything anyone really wants to see, and certainly aren't going to buy).

The general rule of thumb is, you should have two pictures for every minute you are there. You take fewer during the ceremony, about two a minute at the reception, and you take several per minute taking the before and after wedding shots. As I said, it's a rule of thumb, and it varies with the size of the wedding party, size of the family, lenght of time you are there, etc.

The shots you've uploaded look good. Don't sell yourself short. ("no, no photographer, just a guy with a camera") I know that feeling. Been there, done that. But when you are the guy with the SLR and you are the primary guy taking pictures, you are THE photographer.
