I was just thinking about your initial concerns about the overlap between the 10-22 and the 17-55. I'm not sure if a week later it's still a concern, but I have the 10-22 and I find most of my shots are in the 10-14mm range (taking full advantage of the UWA), thus I find no issues with overlap with my 16-35 (migrating to FF shortly). YMMV.
