The only thing I think we have to worry about is the possibility that an advanced alien life form is xenophobic to the point of genocide. And there's no point in worrying about that because they could annihilate us without breaking a sweat. I suppose culture shock may be a valid worry, but we don't have to worry about a new version of small pox- even if their biology is similar enough for bacteria to be mutually infectious, they would have as much(or more) to worry about from us in that regard. Interstellar conquest just doesn't make sense to me, it seems that the effort expended would far exceed the resources gained.
