In my relatively limited experience, scanners really accentuate the apparent amount of dust and surface imperfections on Black and White film (and Kodachrome). So don't be too discouraged, especially if you intend to begin printing in a darkroom.
If possible, you should try to separate the scanning and printing steps. The one digital tool I appreciate the most is the "Clone/Heal" tool. If you can do your "spotting" before the file is printed, it will help.
