From your first post I see you have Rick Schnellman's DVDs. I found them unsurpassed in providing all-around ski knowledge. If you have the time and the stamina, you might do what I did when I got them last summer.
Start watching them now, and take notes. Go through them all, one little bit at a time. They progress slowly. I set aside an hour a day to do this. Take notes on the types of drills he shows, and pay particular attention to the terms he uses for the movements and the explanations of what they accomplish. His DVDs do not prescribe a particular way to ski; he offers drills that give you experiences doing lots of different things on skis with the goal of you feeling what works on snow. He parameterizes the drills. For instance, he'll have a drill where you do something waay far forward, then centered, then waay far aft. If you actually work through his drills on snow, you'll be a great skier by the end.
As you watch the DVDs, target your notes on his definitions and explanations of how movement patterns relate to each other. This will be particularly helpful as you get ready for a season of serious work on building your skills. His ability to explain skiing terms and relate them to each other in one big organic whole is exemplary. He is amazingly organized. If you read here on Epic for any time you'll discover that typical ski terms mean different things to different skiers. If you take lessons from different ski instructors next season, you'll run into this. And it's not only words that are different from one ski instructor to another; they may contradict each other about what you should be doing. This can be quite frustrating to someone wanting to up their game efficiently. Rick's organization of ski technique and clarity in defining ski terms, embedded in those long, slow-to-watch DVDs, will clarify whatever inconsistencies or confusion you may encounter next season. The notes I took while sitting at the dining room table, day after day last summer, have stayed in my mind and served me well.
By the way, don't expect to master each drill on the first DVD fast. There's a lot of one-ski-skiing in that DVD. He says to not skip around, but you can. And after you take the notes, you'll know what you want to skip to.
