I would pick a couple skills to practice every time I go skating. I spent a LOT of time on forward inside and outside edges. Once you can get mostly comfortable on both edges, everything else is a little easier.
Here's a link to a
video on edge control. Check out all the other videos by "BusinessRecovery". I know the screenname doesn't make any sense, but it's all Candadian Hockey development videos (I hear Canadians are good at that hockey thing).
Also, here's a link to the
USA Hockey Adult Skills Manual.
Enjoy!
