Regarding distance... if you feel like doing some summer reading, a couple sound theorists have written a lot about 'point of audition,' based on the same idea as 'point of view.' The idea is mostly about sound perspective, but also subjectivity and where the listener is in relation to the voice. Anyway, this is theoretical stuff rather than practical, but it might help to think in different ways about mic distance, perspective, realism, and that sort of thing.
