Well, I usually have a skylight (B+W, normally) on all my lenses. Not
because I believe that it will dramatically improve the image quality,
rather because it's cheaper to replace a filter than it is to replace a
front element of any of my lenses (hey: lens-caps can fall off). I don't
believe that it (for most shots) will degrade the quality significantly,
but when in controllable conditions, I do sometimes take the filter off.
And I never "stack" filters - that would just be begging for flare....
