This is usually where everyone tells you not to do it. If you don't have experience, including owning the necessary equipment, you will be doing your friend an injustice.

The kit lens isn't wide enough. I recommend getting the 12mm to 24mm zoom for wide angle shots at the reception and learn how to get the light from the SB-600 to cover the wider angle lens.

Make sure you take all the shots that is expected of a wedding photographer. Have a list in your pocket before you start.

Thanks, Larry!!

I can buy the lenses that are necessary (what other lense(s) would you recommend), but can you elaborate on the SB-600? I have already met with the mom and dad from both sides, as well as the bride and groom, so I have an idea of what they want as far as poses and must get photos. Are there any other resouces you can point to?

I appreciate your help- THANK YOU!!

I'd attend the rehearsal if at all possible. I'd make a list of questions and get answers: Photos of the bride getting dressed? Where can I position myself to photograph the wedding party coming down the aisle? Can I use flash during the ceremony itself? How can I get the ring exchange? If it's a religious ceremony, realize that different churches have differend ground rules for wedding photography. I wouldn't want any suprises come zero hour. BE PREPAIRED.
Also, I've had success using an inexpensive Lumiquest pocket bouncer to avoid the likelihood of redeye. I'm not sure but the pocket bouncer might diffuse the flash enough to cover your wider angle lens too.
