If you got the cash, I'd get the 5DIII and sell the 7D. I suspect (maybe someone can confirm) that you will be able to take shots from the 5DIII and crop it in post to something quite similar to what the 7D will make for you. Otherwise, the 7D makes a great backup or secondary camera, and you have enough lenses to be shooting on two cameras with plenty of options. Also great if you do video, you can have two video cameras and great glass. Benefits aside, I'd rather have the extra cash if you don't specifically need/want 2 bodies.
What I can't quite understand is why you would want to buy a 24-70 and a prime 35L at the same exact time. Your doubling up on the 35mm focal length which sits not quite but closer to the middle of the zoom you are looking at. I'd get the body, then later get one or the other lens and only later, get the other lens if it suits a specific purpose (walk around/low light/DOF). Buying too much stuff at once is always going to confuse things, I've done this twice with photo great and if you can avoid it, do, it's a mistake. If I had to start over from scratch (I started with 7D too), I'd have gotten just a body (probably an old used FF) and pair that FF with a 24-70 and shoot on that for a year or better with some weekend rentals of various gear thrown in. Rent whats needed if you get a gig, and only buy more gear if it specifically will make you profit vs. renting it. Otherwise it's just tossing money away. But I can barely follow my own advice, anyways, good luck, you have some amazing kit.
