Now as a wedding photographer, I imagine its a very face paced event?
Im not sure I understand

Did you mean very fast paced event?
If so, yes I guess.
It really depends on the wedding...
Depends on the moments.
1 - photos at home (bride and groom) with close friends and family
2 - photos at arriving to the place where the cerimony will be done (church, garden, etc.)
3 - photos of the key moments at the ceremony - ring change, the kiss, some lectures (I'm not familiar with the traditional american wedding).
4 - photos of the moment when the grooms leave the church/place - the rice and flower toss and so on

5 - photos of the car/motorbike/carriage/whatever they use to go from the church to the place when the party will be
6 - photos of the grooms entering the place where the party will be
7 - photos of the guests, artists, catering, animation crew, etc.
8 - photos of the buffet and people enjoying it

8.1 - photos of the tables and it's contents - like the drinks and appetizers, grilled meats, etc.
9 - key moments like the entry to the dinning room, first plate, first dance, cutting the wedding cake, the bride's branch beeing tossed, and so on.
10 - the fireworks, the balloons, the illumination...
11 - between points number 7 to 10 - photos of the couple in the most beautiful places of the place (it really depends on the place)
I think it's something like this.
Have in mind that I'm no wedding photographer (not yet at least - I'm not prepared), but as an enthusiast, I always see what the photographing crew is doing at weddings, and I usually speak to them to exchange ideas

Also have in mind that I don't know how the wedding are at the United States - In Portugal they are very elaborate and there is always so many moments to cover.
Try to know what kind of wedding your friends want and do a list of the things you have to cover

Try to act naturally and be relaxed - no one likes a stressed photographer.
Try to get people on their natural poses - don't force too much.
At some point, get the tele lens and act as a ninja photographer and get those natural poses that are always the best.
Don't forget to eat and drink and have fun - You will be among friends. That is always a good thing.
Cheers and good luck
