UMMMPH!!! ;-) Oh, well, here we go again.... ;-)
1) UV ("haze") filters have virtually no ability to cut haze...
(since almost all lenses already absorb virtually all the UV
likely to affect the film - the UV is basically a protection
filter only...).
2) Any good-quality filter (Hoya-class, or "better") does NOTHING
bad to image sharpness/contrast, and may contribute to lowered
brilliance only if not multi-coated, and only then under unusual
circumstances.
3) Many of us HAVE experienced accidents that would have dammaged the
lens front element, had the UV filter not been damaged instead.
As to the original poster's question, stacking is not generally
advised (two parallel glass surfaces may have reflection problems;
too thick a filter pack for some lenses may cause vignetting; too
many extra glass surfaces [6 altogether, with a polarizer and another
filter together] may cause image degradation).
Hope This Helps
