17-55 would be great for environmental portraits and full length shots, but I would switch to the 70-200 f/4 for close ups, headshots, etc.
The 24-70 and 17-55 both have very good image quality. One is wider and the other is longer (by about the same amount on each). One big difference is that one has I.S. and is $150 cheaper. If you don't need I.S., you would be paying a lot of extra money for something you don't need. Consider the Tamron 17-50 f/2.8, which has nearly the same quality and features, but is less than half the price. (Read Bryan's review.)

You can't help the fact that Canon doesn't make the exact lens that would be perfect for you, because you have to pick from the lenses Canon actually does make. If that means paying an extra $400 over what the "ideal" lens would cost, so be it.
