Replying to Going out West for the first time

I'm leaving sunday for alta. This will be my first time skiing anywhere, but the east coast and i'm stoked. I was just wondering if the altitude adjustment is a problem, and any suggestions that people might have for things to bring. We'll be there for a week and are staying at the Gold Miner's Daughter at the base. From the looks of things Alta is huge so where is a good place to start, and what are good trails to ski there. Any advice would be great.
