As usually, it's hard to answer such a question without details. Strategies are highly situational, and while some of the time details won't matter that much, they often do. You will play much differently if you have 10BB at the late stage of the tournament and when you're deep stacked in a cash game. 3-betting or 4-betting with pocket aces is a standard play, so I don't see anything wrong with it in most contexts. All in with kings is not uncommon, but it depends on the situation. Were you a first raiser? Was it after a raise? After a 3-bet?
