It's like buying a car: each one of us have a bike/brand we seem to lean towards more. Do you have quite a few bike shops in your area where you can go try some bikes? My personal preference is Trek, some of the ladies prefer Specialized, quite a few of us ride customs. As I said, it's like buying a car - maybe surf some of the bike websites til something grabs your eye, see if your dealer carries it and give it a ride.
As for WSD: again, some women prefer WSD, some hate it. Both my road bikes are non-WSD (actually they're vintage bikes so I guess I"m not much help there! lol). You should really ride several different types to see what you feel the most comfortable with. Kinda like buying shoes!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
