Wedding Photographers...whats in your bag?

Ok, so I have a little extra money to be spending on new equipment to boost my part time photography business, and upgrade some of my equipment. I shoot weddings and portraits (engagements and seniors).

I currently own a Canon 50D, 28mm f1.8, 50mm f1.4, 70-200 f2.8L USM, 430EX flash, 580 EX flash.

I have about $5k to spend. With it I am purchasing a Canon 5D Mark II. That leaves with a little less than $3k left.

What recommendations do you have to fill out my bag?

I am tempted to get the 24-70mm f2.8L but not sure. I prefer my primes and shoot with those about 80% of the time right now.

Tempted also to sell my 70-200 and replace it with the latest Image Stabilizer version.

the 16-35 F2.8 looks good too

Thoughts? Any glaring needs? Someone mentioned getting a 100mm Macro for those detail shots, but I have been doing fairly good doing that with my 28mm

actually, disregard. I figured if I stick with my non IS 70-200 (for now), I can afford the Mark II, the 24-70, the 16-35 and the macro lense and stay within budget.
