Go find some pow.....won't hurt your knees in that 
You're going to have to listen to your instructor, the Candian way of teaching I believe is to use your upper body to lead the board around in a turn. If you read most of what the people here who probably got taught in Europe it'll be the keeping your shoulders in-line with the board malarky which will contradict what your instructors will tell you.
Both are valid....
If you're not taking lessons, something like this:
Keep your weight over your front foot to initiate the turn, then center it as the turn progresses. If you're going to do a heel-edge turn (the one on your heels suprisingly) push you lead foot's heel into the snow, this will help initiate the turn quicker.
Break the turn into 2 seperate parts, the initial turn to the fall line (fall line=pointing down the slope), leave it pointing down for the briefest of moment then continue the turn. Don't try to complete the turn too quickly, don't kick the board round. Keep your knees bent.
Keep away from any shallow greens, unlike skiing it's easier to learn on slightly steeper stuff. Snowboarding is about getting the edge of the board into the snow, the faster you go and the steeper it is the better the edge will bite into the snow.
Something like that anyway....

Aye, but then you probably won't get going in the first place either as a beginner. The technique required being somewhat different since you lean back way more than you will get away with on a groomed slope to keep the nose up. I'd agree with the rest of the advice you give though generally, the only other tip I can add is that when on groomed slopes you should be leaning pretty far forward with most of the weight on the front foot (60:40 or thereabouts), the snowboard won't tip over but you are using it essentially as a pivot point so the less weight you are trying to move around it the better. It is a mistake beginners often make, leaning back, particularly once they get their speed up as there is a natural fear of falling/excessive speed but when you lean back you unweight the front of the board and that relinquishes a lot of control.
