I have done still life work in the past (I almost got my little studio cleaned out this past spring but it seems to be a clutter magnet lately ) and I agree with Scott. Composing and lighting the work is about 95% of the work and viewing the composition on a ground glass as opposed to a viewfinder is great to work with.
Much of my subject matter was similar to what I was working with when I was still working in sculpture (before kids) and seemed to develop from there. And there are still plenty of ideas I would like to work on if I can ever get that little studio de-cluttered!
