Thank you, Godfrey and Bruce for your responses! Godfrey, - let me double check: what is the source of the information you described in the second paragraph: did you read it/got it from a LR developer, or did you conclude it based on your own experience/logical sense... ?
The reason I am asking is that if I smoothened the picture (noise reduction) first, then sharpening _no_ features would produce result different from sharpening the features and then reducing the noise (assuming that things are done in the order that I am doing them, and not in the internal order). What you are saying means that they are likely to apply the changes in the second of the two orders described above. Seeing how the adjustments are syncronized between the files, it makes sense. But 1) this would be different from the way it is done in PS (unless you do it in PS with a mask), and 2) it means that one can observe the magic of uncovering "lost" image information similarly to how it's done in the TV series "CSI" and alike.

Behind the scenes, Lightroom is layering and masking to implement those features. All the other adjustments are just parameters processed in a standard sequence, so whether you set them before or after makes no difference to the rendering although it might make a difference to how you see what you're doing.
