If you're curious about when to play QQ (or any other ranges) Jonathan Little's coaching site offers free ranges for different stack depths. This video gives a good overview of how to use them:

There's also a link to the actual charts in the video's description, though I think you need to sign up for his mailing list to access them.
As far as post-flop playing QQ that takes a little more practice, but IMO if you just get called and there are over cards you should still c-bet. If it's a draw heavy board that bricks the turn you should continue if the turn is a brick, but if the caller has A/K or nothing you might just have to shutdown (unless you think the caller(s) would give up weaker top pairs).
