I recently shot a picture in the US for a PAL (mostly) release and shot in 23.98fps for ease of use in FCP, to stay at 60hz for lighting purposes, and for NTSC release as well. How post production will deal with this, I don't really know yet.
As for filters:
ND 3 (The camera ND filters are 2 stops each, an in between filter can be helpful)
85 filter (the ones on the filter wheel are too much or too little to use with the preset white balance)
Polarizing filter
ND grad filter(s)
I don't think the camera is so sharp that you'll find you'll want to diffuse the image unless you want an obvious special effect. Contrast can be controlled through the camera settings or in post production. I avoid misting filters in general, except for special effects. Of course these are just my preferences.
-good luck with your project.
