High Noise when shooting hockey games (low light) with a A57. Please help!

OP, I would also recommend playing around with your DRO feature. It should make exposing the shots easier when you're having to deal with the brightness of the ice.

Another software you could try to remove noise is noiseware, you can download the community version for free.
I took this using a Sony a200 on a Tamron 70-300 lens at ISO 1600. I used Noiseware to remove noise from the photos.
