ouch, probably the 3 things that you can't do with the overlapping lenses.
and neuro beat me to it, i'll ditto what he said.
just on the 'lots of macro' bit, also consider the MP-E 65. Static subjects (unless you're really good), tripod, and manual focus only, can't use it as a normal lens, but it's a "real" macro lens (5x magnification).
The 100L macro you can use handheld, has the best IS, and can also work as a real lens (makes a good portrait lens).
For a cheap option, which i'd recommend only for static subjects and MF (or a lot of practice and frustration), a set or two of Extension tubes are cheap (kenko are cheapest and good quality).
and for the wide end, consider the 15-85 to save a bit of cash, longer zoom range, just not as good in the dark, if you don't mind taking out a bit of barrel distortion @15mm in PP.
Another option for really wide landscapes is getting the 18-55 IS kit lens for every day, and pairing it with the 10-22 (or any number of 3rd-party versions, Tokina or Sigma make a few good ones).
sports, yeah, the 70-200L 2.8 IS II is where it's at, if you can afford it (or the 70-200L 2.8 half the price, or the 70-200 f4 half that again).
