The very first step that I'll suggest is finding a bootfitter who will help you find the proper boot and fit them for you! The Pro - Ski and Ride
seems to be a shop that is recommended by many on Epic for boots, though since I live on the other side of the continent, I have no personal experience. I hope he's close by; I'm sure other members will chime in with more suggestions on where to go.
As for skis, there are many women's specific models out there in the market today, so you have a very varied selection. I'll let some of the women riders take care of this one, but I think you should be looking at a softer, easier ski to get back skiing on - something a bit wider at the waist might be a good idea, too - around 80mm, perhaps?
Bindings... a lot of skis come with "systems" where they're matched to a specific pair of bindings nowadays, so you're pretty much stuck with that one. This will depend on the specific ski.
Again, welcome to Epic and have fun getting back on the hill!
