Replying to Backcountry skiing: what do i need?

Ok, so I will admit, im a complete noobie when it comes to backcountry skiing/avalanche awareness. Skiing in the mid atlantic before coming out to tahoe doesn't exactly prepare you and tell you what you need to know.

So..

I need some help with this, and start at the beginning. What equipment should I buy? Is anything required before you just go out skiing in the bc? What are some general rules/guidlines that should be followed? What are some good resources to self educate myself and learn more?

Any help would be appreciated. thanks.
