couple of basic questions

[bodie]

First let me say I usually play Omaha & limit Hold em, and am trying to learn the "language" of no-limit betting. Last night I sat down in a B&M $100 1/2 NL table. I only got to watch two rounds before my first hand and the only information I got in that time was that the player on my left had the largest stack and appeared to be running over the table. Another players comment to him as I sat down was, "The rich keep getting richer".
I was in the cut-off position for my first hand and found pocket Aces. There were about 4 limpers, I raised to $15.00, the player to my left called and everyone else folded. Flop: 8, 4, 2 rainbow
I raised again to $20.00 - he reraised me all-in.
What would you do?
Let me add that I am female and that men often will test me because of that.
I will post the Results in a following email.
Second hand:

The very next hand I was dealt A, K.
A couple of limpers to me, I raised to $12.00. Only got one caller, about whom I had no information.
Flop: K, 8, 3 rainbow.
I raised to $20.00. He reraised to $60.00.
What would you do?
The table had just seen me raise with pocket Aces.
Again, I will post results.
I appreciate any thoughts or comments.
