A couple more options to look at:
This is my current mountain. Of all the mountains in the Tahoe area, it has one of the best training programs for skiing and teaching technique (some of the Squaw instructors actually come here to train), there are more hours available to work than other mountains (our reservations are up while most others are down) and they pay more than many other mountains (Squaw is known for abyssmal pay and poor treatment of employees). Northstar also has onsite employee housing. The only downside is the terrain isn't as sick as other mountains.
Yosemite's Badger Pass
It's a small mountain but this is where I learned to ski and teach. The terrain isn't great and the training probably won't be very good either once you get past your hiring clinic but the ski school director, Chuck, is awesome and housing is nearly free ($80 per month incl. utilities a few years ago). There's also an employee bus to the mountain and you can buy a meal card so you never have to cook. You can also climb all winter long and you're in freakin' Yosemite Ntl Park which is one of the most beautiful places in the world.
I've also heard good things about Sugar Bowl.
