Well done! Great stuff you're putting up.
Considering the action and lighting, don't be hard on yourself or your equipment.
Here are my thoughts/questions.
Are you on a monopod or tripod for these?
Are you using your 70-200? With the IS on, or off?
Are these paid shoots, or for fun, or for a minimal return?
And my thoughts:
If I were to shoot this type of sport, without flash, I'd use a two camera setup.
The 5D2 (shooting in RAW!) on a tripod with your 70-200mm @f/2.8 (IS off), probably ISO 3200 or lower, in order to force a slightly lower shutter speed, which in turn would result in some nice background blur. This should work for taking "nice, swooping shots" where the players are skating side-by-side with a 'fairly' predictible path of motion, ideally parallel to your position.
And the 7D, on a monopod, with your 85mm @1.8, shooting in RAW(!), with as low an ISO as I could manage for "grab the moment" shots. OK, so without the zoom, you'll be limited to how far away the "action" is, but in a game, a LOT happens, so you should aim to get each player doing something funky, as well-framed as possible, with the prime lens.
Don't forget that a LOT of pros use fixed focal length "mega"-primes, like the 200Lf2, because they NEED the larger aperture due to poor lighting. But with enough keepers, they can pick and choose their favourites.
Regards for now,
