I am now shooting RAW, and even before I would sharpen later by myself. But 99% of the time I use these settings to develop my shots in Olympus Studio, then tweak them later in Photoshop.
My basic settings:
sharpness: -2 (I prefer sharpening after sizing the image in Photoshop)
contrast: 0 (I may adjust that based on scene contrast)
saturation: 0 (I may boost that on occasion)
