Au Ra are being introduced with but not likely actually part of the expansion. otherwise nobody else would be able to see your character in ARR areas that have yet to buy the expansion.

The expansion data will be downloaded to everyone. You just need the expansion purchased to have access the new areas and quests and such. In this way you can see the Au Ra and new armor on people.

still 99% certain you will be able to become Au Ra without buying the expansion.

Highly doubt it. WoW wouldn't allow you to be a new race unless you purchased the new expansion, and I don't see why this game's expansion, with the new race as one of its selling points, would.
