How to handle poor poker etiquette?

[Death Valley]

I have a "home game" that is mostly friends with some outsiders. We try to run the game as professinally as possible but have one major problem that keeps occuring.
People do not shut up. They do not mean to cheat, but people keep talking about their hands "Oh I would have flopped trips", "I should have called Id have hit my straight" even the occasional "Do you think I should call?" (asked to an observer) and sometimes non-english is spoken.
Some of this is poor etiquette, some could be considered cheating so what is the best way to handle this?? I do not want to kill any hands (ie. rule the hand dead). I dont want to kick people out, but how many times do you have to remind people?

How would you/ have you dealt with this problem.

BTW: This is a 1-2 NL which plays very deep (avg 3-400 BB stacks) while this possibly shouldnt matter, I want to point out that this game is not just for fun
