The redhead was the prostitute from Winterfell Theon was obsessed with... I forget her name though. How apt.
Littlefinger explicitly calls it out though, when he's admonishing her ("Is that how you do it in the North?")
Very minor book spoiler:
As for the necessity of the scene, and others expository things...
Littlefinger seems to be set up as the vehicle for exposition in the series. More specifically, he seems to pick up a lot of the slack from scenes left out or in internal monologues or description. Case in point: in the book, the Hound's back story comes from the Hound*, not from Littlefinger.
That said, I found the scene completely extraneous and, perhaps more damning, lessening the shock of Littlefinger's betrayal. It didn't need to be in the episode at all.
Otherwise a solid episode overall. One point that should have been made in the episode is that Arya and Sansa are still in King's Landing.
* Though this scene should have been in the show; it's a pretty important scene for establishing future story lines.
