I played hockey all my life, the OHL, QMJHL, UHL for forearm strength take a maybe 12 inch piece of wood and hang a 2 pound weight from it, with the weight touching the ground. Hold your arms straight out in front of you at shoulder height and DON'T bend your elbows. Now simply rotate your wrists keeping your arms straight till the weight reaches the piece of wood. Then unravel the weight in the same fashion that you brought the weight up in.
The key to this exercise is to keep your arms straight, any bend and it totally defeats the purpose of the exercise.
As for skating, just keep trying rolerblades work great but don't really give you the same range of motion as regular skates. Just keep an eye on your stride when you skate and make sure you are getting the most out of all your strides.
Good luck, I hope you enjoy playing the game, keep us up to date with you progress.
