On translations and google in particular, my understanding is that it is up to each Wikipedia community to decide how/if to use translations as a whole, and whether google's translation tool is useful or not. I'm not aware of anything that either binds us or restricts us from using translation technologies, and my guess would be that you should decide on the basis of your experience. If you'd like to get a broader or comparative view, my suggestion would be to check in with the Board, ask Foundation staff members you know, or perhaps post to foundation-l and see if others have useful experience to share.
