New Player Needs Some Advice

Hello, fellow BlackJackers -

I am new to the art of blackjack (and yes, it IS an art). I have
played the game on my computer and on a friend's Palm Pilot, but will
be making my first trip to a casino to play it live! And needless to
say, I'm excited about the challenge. I don't mean to brag, but I'm
GREAT at the game on my computer. I head to Atlantic City prepared to
win a lot of money.

Here are two questions for the more casino-experienced of you. Is
there a limit to how much money I should win before walking away? I
would hate for the casinos to think I was somehow cheating. Because I
plan to go back frequently when I need to make money for specific
items in my life - vacation, car repair, etc. 

One more question: I am fully aware that you don't hit on 18-21, but
what is the general consensus of the group for the following numbers:

11, 12, 13, 14, 15, 16, 17

My gut says hit on everything up to 16, but I'd love to hear another
opinion or two.

See you at the tables!
