You got good advice right in this mail.  Early (in the process) noise 
reduction followed by setting the levels (white and black points and 
mid-range brightess).  Viewer 2 does do noise reduction but, 
unfortunately, it's so slow as to be pretty much worthless.  I stopped 
there thinking it wasn't worth it to figure out how to fiddle with the 
histogram.

If you buy PhotoShop Elements (less than $100) you'll get ACR which will 
allow you to do early stage (capture) noise reduction.  Fiddling with 
the levels is a simple task of moving sliders around.
