lens hoods would not adversly affect your picture in anyway so it's fine to leave them on even in low light conditions. if you want to use the onboard pop-up flash though, be careful because sometimes the lens hood will block off part of the flash coverage.
a good, multi-coated (such as B+W's MRC) uv filters should not reduce image quality in any significant way. it's better to go with no filter if you are shooting directly into the light (like a street lamp or the sun), even the best filters may cause more flare than no filter at all.

Hmmmm, I'm wondering, does anyone know if you should still use a lens hood even in low light conditions? Like, indoors or on a wicked cloudy day.
And do UV filters reduce image quality in any given situation? Low light, lotsa light, ect?
