I use lightroom as my
RAW processor, so do 'whole of image' edits in lightroom, things like:
Cropping of the photo
Exposure Adjustment
Horizon levelling
etc
Then in Photoshop, I do my other adjustments:
Any cloning (removing dust bunnies)
Using layers and layer masks to work on certain parts of the photo
Saturation adjustments (if I want the photo more vibrant, or a mono conversion) I often saturate some parts, while de saturating others (not selective colouring) as I don't remove all colour from areas.
Levels and curves adjustments
Brightening or Darkening specific areas of the photo (vignetting for instance)
Sharpening
This is just how I do it, each person needs to find a
workflow that they can use. I probably do not use all the features of lightroom and could do a lot more in it, but I started out with lightroom V1 beta (as I came from the Pixmantec
Raw Shooter brigade), and at that point lightroom was DAM software with a
RAW processor built in. I got my
workflow down and like, it and have thus stuck to it. I know several people who use Lightroom a lot more intensely than I do, but it is what works for each of us.

Pixmantec Raw Shooter : was a damn fine
raw editor, that Adobe purchased the company to get access to their
RAW algorithms so it could develop Lightroom.
Raw Shooter was the engine behind the original Lightroom. All people who owned
Raw Shooter got a free copy of the early versions of Lightroom, including beta's of it before it was available to the public.
