Ed,
The high pass layer is pretty cool. It creates a nice blend of sharpening and contrast unlike any sharpening filters in Photoshop. I use it when retouching at work all the time. Most high pass filter tutorials only suggest using "overlay" as the blending mode, but I've found "soft light" and "hardlight" are good alternatives depending on the effect or the degree of contrast you want.
