Peregrine_Tergiversate; those are not the only things I asked, I have more answers for you in I think the second page of this thread (I'm not sure if you saw them, but you only quoted the startpost of this thread).

As for the modding questions, I emailed them to CA England, who will forward them to their Australian collegues (who work on that and balance issues and the like), they said that it might take around a week to get answers on those questions.
