I use the sharpening program from the Pixel Genius and it does what I want. However, if I were doing it now I wouldn't buy it. Instead I would use Glenn Mitchel's FREE programs at

.
I tested and really Glenn's work as well as what I bought.
That said, once you decide on a method for processing all these shots,I recommend reading Bruce Frazer's Real world Camera Raw w/ Photoshop CS2. It will teach you how to process all those shots to what ever level you need for your purposes with the least hands on.
