First, we know ritual hand washing is not a "Chabadism". Nevertheless, netilat yadayim is primarily a hygienic cleaning, as opposed to mayim achronim which the sages identified more as a spiritual washing than as a hygienic one. Cleansing oneself of the "evil-spirit" is associated with the mayim achronim. In my mind, rabbinic ordinances are just that and, as such, are not commanded by G-d. That being said, I think a little soap during netilat yadayim would be promote hygiene.
Second, I didn't say shokeling is a "Chabadism". Anyone who has grown up frum knows this. But shokeling is not a competitive sport, which it appears to have become at Chabad. I never saw this as a kid in the old-style shuls and shtiebls.
You have to know what is required and what is not. "Rabbinical ordinances" in this case are required by Halacha especially when its done by Beit Din. No one can come today and "nully" their decrees, and even the Torah itself says to follow the Hachamim, especially when it was the Beit Din Hagadol who made these things. Even with Netillat where Rabbi Akiva was the opposing view, he never the less used much water when he was in prison (opposed to his own view) since the majority ruled that way.
About "shokeling" people can do what they like. But according to Sefardi custom and I think based more on "kabbalah" if I'm not mistaken it is better to stand still. But either way davening is davening, and that is the important part. If shukkeling creates better concentration do that of otherwise do otherwise (like remain still).
