To be honest, I don't see the difference between the two. But the idea of applying it in small measures just takes that risk of producing jaggies. Personally I like to mix it up, it all depends how I feel to be honest.

"How do you feel today, Justin?"
"Oh, a little pissed"
"Why don't you go sharpen some photos?"
Roots: I use USM usually in one shot, but sometimes apply it twice or three times. The values are in the range of 100/0.3/6. Justin might actually be on to something in regards to it being a 'mood' thing...

With L glass and a good DSLR you really dont need much sharpening. It all depends on your type of camera.
I can second that. It also depends on the how much you zoomed (100mm barely any sharpening, 400mm much more sharpening) & the cropping you have done to the pic (no crop—less sharpening). For uncomplicated photos I often use the auto-sharpening, for more difficult cases I usually try USM, sometimes also combined. I also tried this gradual sharpening but couldn't find any advantages.

I use two steps after resizing my slide scans (from around 3000 pixels to 1024 pixels wide): 500%/0.2/5 and 300%/0.2/0.
Explaination: By using 0.2 (instead of 0.3 or higher) small details are sharpened better, but it is not as strong. Therefore I need two passes. The 5 in the first pass is to reduce the grain, I guess this is not necessary with a digital SLR output.

I have a dumb question. I use Paint Shop Pro, and it has an unsharp mask as well, but the setting are different. In PSP, the format for the USM filter is:
Radius (0-100); Strength (1-500); and Clipping (0-100). All numbers are whole, no decimal is available.
Can anyone please tell me what settings should be used to sharpen a photo without adding jaggies? I understand it will vary slightly by image, but can someone give me a starting point?
