Hi Svig & welcome to Pixalo. I also have the D200 & money permitting the
Nikon AF-S 17-55mm DX f/2.8 G lens will make the most of your camera's ability, plus offer a decent zoom range for wedding photography. If you have more time to compose shots etc at the weddings, then a set of decent primes will always be best. Your spoilt for choice here with
Nikon lenses , so your better off waiting for someone who shoots weddings to advise on best focal ranges
