There's a lot of different ways in which the Au Ra could be implemented. I suspect that the developers may simply allow them to play through the original story and claim that their presence during such content is simply for the sake of game mechanics.
It's also possible that they may simply start out at a higher level or have their own instanced starting experience that builds them up before thrusting them into a point where the story makes sense.
Either way, I favour the idea of just being able to play them anywhere to prevent people missing out on past content just because of their chosen race. That's pretty much how WoW deals with such things, after all. You could make a blood elf during the first expansion and still play through the original content even though in terms of the canon story a lot of the threats had already been dealt with.
So long as people don't start claiming that their Au Ra was actually the one who took down Ultima Weapon I don't think it'll be very confusing at all.
