If you follow the rule of "radio buttons are fro single choices in a set and Checkboxes are for multiple choices in a set" then the problem becomes simpler.
The only time I would have "choices" pre-selected were if I had a business imperative to drive people toward a particular choice. All checkboxes checked would be because I want visitors to have All the selections. That's the "opt out" choice and goes against permission marketing concepts. For radio buttons I would have one pre-selected only when I understand that most visitors select that choice; that becomes a kind of usability accomodation.
