I have a few add groups that get very little traffic -they are seperate sizes of a product. Would this effect my overall quality score for a campaign, then I should think of getting rid of them, or are they harmless?

Quality score is per keyword not per campaign. So it shouldn't harm your quality score for anything outside of this ad group.
