I think you're preference for Campy seems to narrow the field a lot unfortunately.
At least I don't see Campy on a lot of stock bikes outside of Bianchi. And even Bianchi only offers it on a few models. Maybe others know of some stock bikes that are women friendly that offer campy.
The other route you can go is to acquire an older frame (i'd go steel but that's my preference) and build it up with some older campy group. I suppose if you've got the $, you can get a new frame too if you don't have the patience to wait for something to come your way in your size.
The latter seems like more fun as you can customize as you like.
I guess you can get lucky on the bay or on craigslist where someone might have customized an older bike to have campy parts and such.
Good luck.
BTW, welcome to the land of somehow acquiring more bikes. :/
