Take a look at this.
http://www.neatimage.com/index.html?37
I've been playing with the free versions for a couple of hours now, 
there is an option for sharpening
in r, g and b channels separately and in different frequency bands,and 
that in addition to the noise reduction
function. Can any one else comment on Neat Image? It looks pretty 
impressive on the couple of shots I tried it on.

BTW : also found a plugin called PTlens which corrects for various 
digital cameras and lenses in PS.
has anyone tried it, it's free too.
