Whoa...your whites are a bit harsh...way to "nuclear" on my monitor especially the boards in the first shot. Also, something else strikes me as odd, although can't quite say...maybe too much overprocessing or oversaturation? Did you use any NR?
For hockey you should use a custom white balance taken from the ice surface. It can help a ton when PP images. Also, don't be afraid to bump your ISO to 800 and then you can get a bit more flexibility on shutter speeds, DOF and the like. If you are at the Saddledome for these (?) I suspect your light may be pretty good (heck if you could get away with 400ISO that's pretty good!) and you could freeze the action better. There should be minimal noise with the 40D.
Cheers!
