How much bodily contact short of Eastwooding is allowed?
Quite a bit, actually. Especially up against the pole. Eastwooding is very strictly defined as contact involving an embrace or a push to the ground. Pushes to gain position, body checks, etc., are just fine. Dan used a lapse in the early rules to physically grab the opposition in a bear hug and tell his teammate to play one-on-one. This is the essence of Eastwooding; actual restraint from play. Knocking out of position is a big part of the game.
