Second picture's from Batman:the return

First and last are from Batman incorporated (2011)

I was reading Batman Inc as part of Morrison's run, and I saw this miss Brown... I remember seeing a Batgirl with blond hair earlier on, but I chose to assume it was a new bat-fam member I didn't know of.

I've read infinite and final crisis, but I don't remember anything about Stephanie coming back to life. Also, for some reason, her return is associated with infinite crisis, even if she isn't shown until much later (or so I've heard). Why?

Bonus question... if Steph's Batgirl, what is Cassandra's name?
