"Proper" technique seems to change every year, and what is efficient for you is something that you need to experiment with. Clinics are great places to learn from instructors, and from other skiers. They are usually inexpensive (or free...at least around here there are tons of free clinics).

My uphill tricks (and I'm pretty speedy uphill): maintain an exagerrated "athletic stance" with flexed ankles and bent knees, drive with the knees, and most importantly look forward (not down at your skis). I kind of do a little "crunch" with every pole plant if I'm v-1 ing. With v-2, I pretty much crunch on every plant (but I'm not in good enough shape to V-2 up steep hills ...maybe next year).
