All, Resolution is only half the battle. Ensure that youre getting adequate pixels along the longer dimension of the image. 8000 without interpolation is a good starting point. Consider scanner quality as well. If youre looking to "scan once" make sure youre using a publication quality scanner such as an Imacon, Creo, or Kodak. I dont exactly agree with no color correction in Photoshop. Its best to keep your scanner calibrated and have it output the image to Adobe RGB 1998 as a working embedded profile. The scanner calibrations wont change very much, but it is something to watch.
