A Vietnamese wedding

So after a week I bought my dSLR (about a year ago), my friend asked me if I could shoot his wedding. I've never shot an event before let alone a wedding and I never had a dSLR before, luckily my previous point and shoot had all the manual functions, but I still didn't know what the best settings were. My friend assured me that I'd be able to do the job even though I was still a noob, I guess he just wanted someone to snap some shots, not needing the pro touch. But as I was reading up and getting inspiration from other wedding photographers, I couldn't help but try.
