What you ski in is so common that most ski makers accommodate it, although the powder-to-ice transition is a bit tough. K2's Axis ($625) is a highly rated all-around ski. So's the Volkl Vertigo G2 Energy/20/20, at $575. My advice: Try to rent skis for a few days, and get some out on different terrain and different snow to see what you like.
Beyond that, I should think the Beta Ride 10.50 would be terrific for you. It's uniformly rated as a top-rate all-mountain boot, comfortable yet with plenty of support. The only drawback, as you mention, is the price$600. I bet you can find one for about half that at some ski shop, though. It's clearance time of the year. Otherwise, lots of lesser-priced boots work well in changeable ski conditions. Salomon's X Wave is a comfortable, all-mountain book that sells for $500. I also like Tecnica boots - check out the Rival RX Ultrafit ($525). It's also a very roomy boot which might help you better accommodate an orthotic.
