Please note that characters, items, and friends lists do not transfer across regions. Playing on a different region's servers means you'll be creating characters and friends lists specifically for that region, and you'll be accessing the gold-based auction house for that region.

Answer 2

No, this is impossible. The Auction Houses are region based and items have to stay in your region.
