Never used that lens, but it's very very wide and you could get some distortion. Did you look at the 17-40L also? The 17-40 is my every day lens.

It's an EF-S mount lens -- it's only meant for crop bodies, so the edge distortion one would expect is less of an issue.
The 17-40 would be a very good alternative, particularly as it's an L-series lens, and using it on a crop body would give an extremely useful focal range for most purposes. It also has the advantage of being just fine for usage on a full-frame body, so if you ever decided to change to a FF body, you could keep the lens (the 10-22 would NOT work on FF).
580EX II -- no experience, but my other Canon flashes (550 and 420) are fine; I'd assume it's better if only due to superior guide number versus my flashes, but I haven't really found the need for more power/faster cycle time.
