Replying to Questions for people that live in Tahoe

So I was trying to figure out what to do for my 21st birthday, I think I'm going to hit up Tahoe so I can ski during the day and get wasted and gamble at night on the Nevada side, but I just had a couple of questions because I've never been there.

Which resort is the best for a pow day?  My birthday is Dec 16 so I'm hoping there might be some epic snow with a bit of luck.  I've already gathered Squaw and Northstar have the best parks, but I have a good park at home, I want to just get as much gnarley shreddige as possible if the snow is good.

How far is Heavenly from Northstar/Squaw?  I got a buddy that lives and works there who I want to visit.

How far are the Casinos from the resorts?

Which part should I stay in?  And if anyone knows some nice cheap places to stay (emphasis on cheap), it'd be appreciated. 

Also, are there any good package deals on lift tickets for like 4 days-a week?  Or deals where you can ride different resorts?

I'm driving up there from LA, so getting around won't be a problem, I'll have a car with chains.
