You're going about it all wrong. Most of their game is not based on ice blocks, grabs, desynchs, infinites, etc. All the new upcoming players see these being done in a some videos and think "omg, a grab equals a stock so I'm gonna devote all my time practicing grab combos and getting the infinite down and then I can own too!" True, grabbing is the most damaging opening for the IC's, but it's not all about getting the grab. And when it is, you have to figure out how to create openings. Basic ground work (dashing, dancing, wd'ing most importantly) are the key to creating such openings, and by far the most important part in learning to zone the field with them. Not just for grabbing, but for the jabs, smashes, and everything else really. I like pchoo's list, it's pretty solid and right on for the most part. I also like what he said at the end about the order in which to get that stuff down. I learned the same way, and I'd say it's pretty effective. It can never be repeated enough though, that your basic foot work is the key to a successful progression of the IC's metagame, and is really what all your objectives should be based on...
