I got it all sorted.. for some reason the box was having an off day.. Coupled with the fact I had fun_plug on there which was having a whole different set of issues. After removing it all by putting it into another linux box all is well again.
I still have issues (lack of speed / permissions problems with multiple users) with my network shares on OS X but I'm used to that now.
Glad everything worked out. For many users, fun_plug isn't that much fun to use.
