i would give clipfinder another try. you might have to try a few different settings, as documentation is not great (although I have not seen the latest paid for version).
with clipfinder you are using an xml workflow which gives more flexibility than edl. you also might want to clean up the FCP sequence first if the editor gave you a sloppy project (imagine that!) - it's much easier to deal with a on or two layer video track in color.
or wait for davinci 8...
