Silveretta 500's. They work real good with any boot that has a toe and heel bail. Any plastic boot, not just Koflachs, suck to ski downhill in. That's just the way it is. But you want 'em for transportation not making turns right? Plus if the snow conditions are good and you are a decent skiier you can make turns in mountaineering boots.
As far as skis, go to Goodwill or Value Vilage and buy some old alpine boards at 185 - 195 cm. Those will treat to just fine. If you want to get fancy and throw down some cash you can get some shorter fatter boards which are nice because they are lighter, more maneuverable, and will float better in deeper snow. But then you have to pay more money and they also won't track as well on firmed up snow.
