Hi J00ston,
Thanks for the post. When I first started shooting weddings five years ago, I started very simply. I did not buy the best lenses on earth...I purchased very good ones. I think that I I were to do it today, I would do the same thing.
Other lenses you did not include that are well reputed (but that I have not used) are the Tamron 28-75 and the Sigma 10-20mm lens. This will provide you the full range that you need at a very affordable price (less than $900 US for both, I think). Once you have the 'basic range' taken care of, I think you need to be more selective with your lenses. One of the great things about being a professional is getting a different perspective from others..specialized lenses that fit what you are trying to capture are important. Once again...get the basics first though.
I do agree with Pete, there can be some great deals on e-bay...however, just be careful from whom you purchase. i.e. buy only from folks with solid reputations and of course, still be wary even if they do. My own account was hijacked on E-bay for a short bit.
