Here's a recent video tutorial I put together for how to sharpening your images using the High Pass filter in Photoshop. It's my favorite method of sharpening images prior to final output.
The only addendum I would like to add to this video is that you want to be pretty frugal about the amount of High Pass filter you apply. Applying too much can present haloing in areas of high contrast and this will ruin your image. Apply only enough necessary for your output medium, this may require testing. Stay tuned for a follow up tutorial showing how you can automate this whole process to ramp up your productivity.
