I don't have a D5000 and have only briefly held one, but will try to answer your question. From what you describe your problem seems to be with the default Picture controls: Color Mode, Saturation, and Sharpening. If you check the Exif data (Color Mode, Saturation, and Sharpening) of an image captured using Landscape exposure mode and write them down. Then place the camera in P,S,A,or M exposure mode. Go into the camera Shooting menu under Picture Controls and adjust them to match those that you found in the Exif data. This should provide more of the "Pop" you are looking for. Good Luck and Enjoy your Nikons!
