Questions and a hand

[sMethod]

I'm fairly new to the MTT community online, I'm mostly a NL cash game player but Iv read Sklanskys Tournament Strategy for Advanced Players and I have about 100 or so under my belt but I don't think my game is nearly as refined as It could be. I was hoping to have some MTT specialists let me know how they change gears throughout a tournament. Is playing conservatively in the beginning and more aggressive toward the end still the basic strategy used by the best pros online?

How light should my open raising range be at 20bbs compared to 10 before I get in the money?

How light should my open raising range be at 20bbs compared to 10 after I get in the money.?

At what point is it better to open for a smallish 3-4bb raise rather than just pushing (How deep)?

This hand my brother was over my shoulder and was like omg how could you call that! He had been watching the whole tournament and never saw me take a single flop with KQ mucking it regularly, now I had cold called an allin pre flop with it. Was I justified because of stack sizes to make this call?
