Take a look at the Parsha pictures many Rabbeim send home…The Avos with Streimlich. Additionally, I had a Rosh Hayeshiva who told our Shiur, that if we don’t wear our hats and jackets in the street we will lose half of our ability to shteig.
As far as shokeling, I heard a source that we serve Hashem with Ahava and Yirah, hence, shokeling front and back.
