I think you can do the shoot with with your Sigma 17-50 2.8 OS and the Sigma 50-150 2.8 OS on two bodies and not have to worry about switching lenses.

I would suggest having a total of 6 16Gb cards if possible.

If I lived nearby I would be glad to help you out just for the fun of it
I agree with Joel except the 6 16Gb cards
I know the 7D uses more memory per image than my 5D but 2 16Gb cards is more than enough for most weddings. I think twice I had to go for my second card on my camera so I used three cards total. This is shooting raw. I spend about 8 hrs shooting a wedding and on average take 1,000 pics between the two cameras with plenty of card space left on both. If I am giving my customer around 300 images from the 1,000 I am shooting there are plenty to choose from. The largest wedding I shot was an east Indian wedding and shot almost 1,800 pics. It was hardly any time to take a break and I was exhausted afterwords not to mention having to process 1,800 images.
I think two more 16Gb cards will be plenty.
