Not sure what you mean by quantitative strats. Aren't they all?
But Natenberg (Option volatility and pricing), Cottle (I thought "Options, a hidden reality" added a new dimension to options books), and the billion bits of info you'll find in the options section of this board.
You've probably already discovered that the options part of this board is a different world from the rest when it comes to respect, and people just simply willing to help others.
These threads are lengthy, but they are a blast to read (well, for you and me anyway) and there is a ton of info, and you will be able to pick out the guys who are truly knowledgeable when it comes to options.
