I agree that the black dots look like light leaks into your darkroom, or from pinholes in the black bag. As for the scratches, generally speaking white lines indicates scratches on the base side, black lines on the emulsion side. These lines look light enough that a little "nose grease" on the base side of the film will do the trick.
Hope this helps. Wishing you the best on your journey into medium format.
