What does the Sharpness control on my DSC-T7 do? Does it apply a post-processing filter to the image? If I increase the sharpness, is that all just software, ie, the same thing I get photochopping it? Or does it actually capture greater detail from the CCD?

It is a software solution. It actually adds artifacts to give the impression of sharpness. The sharpest image you can get is with the sharpening at the lowest level. That doesn't mean it will look sharper, but if you blow it up it has the most unobstructed detail.

I always shoot with minimum sharpening and contrast for post processing. I have to do a bulk action to make them look good for viewing, but I also save the originals for post processing. Minimum sharpening gives the purest image and minimum contrast gives the greatest dynamic range.

Thanks for the information... when you say "minimum", do you mean the default setting of zero, or some negative value?

I use the lowest settings my camera is capable of. If you don't want to mess with a batch action they don't really look great though. Most people find the defaults to be a good compromise.

I also use the "minimalist" setting for pictures I know will be printed on large format paper. There IS a noticable difference. (This is not camera specific, I'm talking pretty much accross the board here)

BUT, you do need to work on the pictures more than "usual". Nothing is free so they say...
