The only setting that somewhat of interest here is Preferences -> Data format. If your raw converter can take advantage of DNG in floating point, use that.
If your raw converter deals with black level correctly (allows to open the image, the contrast of the image from the raw converter is good by default, no weak shadows) you can leave Preferences -> Subtract black level unchecked.
