I'm going to weigh in on this one too, as it's close to home.
first question that needs to be answered is what do you want to do out there... If you want to shred some western faces and be totally rad, then get AT gear on alpine skis with full length skins. If it's not dynafit then it's probably going to be heavy for just touring along the range.
If you want to tour and enjoy the experience then get some 3 buckle plastic tele boots, a pattern based ski with a good sidecut (the Madshus Annum seems popular at Paddy P). you can bring skins as a backup for unprecedented levels of ice or if you want to climb steeply. Make sure the bindings have a free pivot tour mode.
If the sun is shining you can try dropping the knee as you traverse or cruise down mild slopes. otherwise just stick to your parallels like most telemarkers do when the going gets tough.
If you want to move quickly but you also want to hate yourself then get XC gear or really light telegear.
