I think these look pretty good. I am not sure what the lighting is like there but where I shoot at I have to say I have the worst lighting in the world.
Here is my set up and settings I use most of the time when I shoot.
1D mkIII 70-200 ISO 2000 AV Mode F2.8 and I let the camera pick the shutter speed normally its between 1/400 and 1/640 I also set my EV to +2/3 and I have pretty good results with this set up.
I also wouldnt use a mono pod for hockey, your getting fast enough shutter speeds that you don't need one. Personally thats a tell tale sing your not a pro and the group of guys that I shoot with make fun of the mono pod / lens hood combo.
these are some of my resent shots with this set up.
