Some comments from me. Sorry if they are not that good as I'm still not thinking well after a flight back from Vienna.

I think a telephoto lens doesn't suit a wedding very well. A wide to medium telephoto zoom lens like what maniac said should be a better choice for capture the moment pictures. A telephoto lens would be great for posed pictures.

While the moments captured are good but composition and WB can be better. There are some warm pictures posted.

I'm sure you will be shooting great pictures with the right gear, especially with a proper external flash.

Thanks for sharing.
