If I want to print it large then I will sharpen it and save the altered file keeping the original Tiff for future use.
If I am going to use it for the web then I'll resize it and then sharpen it before saving it as a Jpeg.
These two uses have very different sharpening needs so I keep them separate. Typically a file for printing will need a bigger radius and higher percentage to give the final paper picture a bit of bite whereas a web file will need a more careful treatment to make it pop on a monitor.
