If you have the 10-22 then I wonder if the 17-55/2.8 will still be worth it as both of the lenses cover the wide angle range. If you have hard time looking through your 17-85 below 24mm, the 24-105 @ 24mm on FF is no better. The 24-70 is considerably better in terms of distortion at both ends.
Personally, I would add a 50/1.4 to your kit and forget about zooms.[]
