Stuart Walker has written some excellent books on wind and stategy, along with other sailing tactics and boat handling books. I suggest you get and read them...all. I've got about 5 of them, you can borrow if you'd like. I do not have "Sailor's Wind" but am going to get it.

Also, Frank Bethwaite has written some great stuff in his HIgh Performance Sailing, get it, read it, use it.
