Their first meeting as Batman and Catwoman was in the Gotham park 5 years before in Valentine.
Catwoman never found out he was Bruce in New 52, except in the cancelled issue where she figured out he's Batman because Batman and Bruce have the same kiss.
In Rebirth Catwoman found out Bruce is Batman pretty early on, told in one of the Annual drawn by Lee Weeks, but I don't know the details. They first met as disguised veteran and prostitute in the streets, then as Batman and The Cat at the boat.
I don't know if they hang out in Golden and Silver since she's mainly a criminal then.
