interest in a video? NLCASH

Very good video, thanks for posting this. As a newbie to the HU games, I have two questions:
a) is opening 4BB OOP/from BB and 3BB IP/from SB standard? Seems to bloat the pot OOP, doesn't it?
b) I read HOH2's HU section and it suggested limping from the SB if the opponent doesn't raise you much because 1) you will have position 2) no hand is more than a 1:x dog against a random hand. I take it that standard here is to raise so you can take it down preflop and for disguise, right?
