    I have heard here and there that when using Component cables you should have your sharpness as low as possible. Is this true?

    What everybody has been saying is, calibrating the TV with the sharpness in the off position. Sometimes off is at the left, sometimes it is in the middle. The meaning of sharpness off is "flat video frequency response" (there is still an upper limit which is the horizontal resolution limit). If you have AVIA or Video Essentials, find the pattern with upright white lines with black spaces between getting thinner and closer together at the right. You want to set sharpness so there is no band of lines that is more strident near the right side of the screen.
    Also find a test pattern with isolated white upright lines on a dark background, for example a grid. Sometimes you will find that if you increase sharpness, echoes or ghosts appear to the right of an upright white line. This is called "ringing". You can adjust sharpness to your liking but it is better not to raise sharpness to where these ghosts become obtrusive.
