I did the City & Guilds level one, which was fairly basic and alot of the stuff I'd taught myself over 20 years messing with a camera, but it was good to refresh on some stuff and also learn some extra bits and pieces that I'd not picked up on.
It did make me photograph things out of my usual zone as well for the projects and I met some very nice people, so for me it was worthwhile. They also bought in a pro magazine tog for an evening talk as well which was good and he critiqued any photo's we wanted him to look at.
Your camera would probably take good photo's at a wedding, but I don't think it's enough to use as a pro wedding photographer, you may find you need something a bit more robust, probably another spare body, more batteries, more lenses, flashguns ..... the list goes on!
