I'll throw one more vote in here for a road bike... they are so much lighter which makes climbing soooo much easier....
Also if you do not get a WSD ask the bike shop to put WSD shifters on for you unless you have long fingers (try both and see what works best of course)... I had my LBS put the womens shifters on and it made shifting and braking much easier... especially braking when in the drops!
Good luck with finding your bike! I'm actually selling a WSD Lemond on eBay right now... just got a Litespeed Tuscany... "cause Santa LOVES me!
There is a fine line between "hobby" and "mental illness".
