To help your skating I recommend a book by Laura Stamm.
http://www.amazon.com/dp/0880113316/?tag=robitaille-20
The book explains how the edges on your skates work etc. It is very important to understand this if you want to learn to power skate.
In order to use this book you have to have some ability to read and learn from books. The book is sort of technical when it comes to technique but if you are able to understand this sort of instruction, it will help you.
For buying equipment to play hockey, I am going to recommend that you spend your money with some sense of priority. You should spend more on things that provide more impact (or less lol)
1 Skates - do not be frugal. Get the best you can afford
2 Shin Pads - you get hit a lot on these, pucks and sticks
3 Gloves - getting hit on the hands hurt and most of us have to use our hands at work
4 Shield or cage - Getting cut on the fact sucks. Trying to explain why you have a black eye or a ton of bandaids while at work is worse.
5 Helmet - I have never fallen and hit my head. I have been hit in the face by sticks and pucks but nothing ever serious
6 Elbow pads - you will fall and it is a natural fall breaker. These also protect you from sticks
7 Pants - These mostly protect you from the pucks but occasionally from sticks.
8 Shoulder pads - I have only been hit in the upper body once and this was last week. I have had a bruise for 2 weeks now. I played without shoulder pads for years, it is mostly to protect you from the puck but a little from sticks.
There are miscellaneos things you need:
Cup/Jock - I have only ever been hit in the groin once and it was a guy who did it on purpose in front of the net (Hi Brian you prick). I have never been hit by the puck in the groin. They have shorts that hold your cup in place and also hold your socks up using velcro.
Socks - you will need a pair or 2
Tape - You need tape for your stick but some use it for their socks/pads to keep things in place
Jerseys - you need a dark and a white jersey. A kings Jersey works fine.
To get your skates to fit all the time:
use very thin socks (or skate without socks). Use the waxed laces. They don't move around on their own but the skates are harder to take off or put on.
To get your foot correctly in the skate:
Put the skate on your foot and then
bang your heal back into the skate
+
bang your foot down onto the blade.
When you start tightening the laces, you want to push your foot down and back.
The heal should be locked into place in your skate. Your toes can move freely but your heel is your base. If you foot is sliding around at the heel, you need to re-tie your skates as instructed above.
Skating tips:
It is important to understand your 4 edges (2 per skate) and your flat.
Your weight should always be OVER your skate. Watch when Kopitar is skating, his but is down so his body mass if over his skates. Knees bent, but down, head and chest up.
When turning, lean your upper body over your skates. This seems to be impossible but it is not. If you are turning to the left (counter-clockwise) your skates are leaning to the left (like a motorcycle) while at your hips, your upperbody is leaning to the right. You are putting your weight on top of your skates.
Good luck.
