Stacking Filters: Is It OK?

Amber, there's no rule that says you can't use multiple filters, but there are some potential issues to consider: First, there is a chance for more flare to occur, as each fulter adds two air/glass interfaces. Second is the (minor) chance of increasing optical distortion - if you use top-quality filters like B+W, then you should be OK, but less-expensive filters may not be as perfectly flat and thus can cause some distortion on their own. Adding more filters just multiplies the effect. Third is the possibility of vignetting - that is, having the corners go dark because the filter rings themselves extend far enough to get caught in the picture. Now this is only an issue when you use very wide-angle lenses (like 24mm or less on a 35mm film camera), so if you're using normal or tele lenses or have a DSLR with a crop factor this is very unlikely. If you do decide on multiple filters, I'd put the polarizer on top.

It's not only OK, Amber, it's normal. Cokin style filter holders come with multiple slots just so you can add several filters at the same time. And while Bob's points are quite valid, it is a very good idea to leave a UV filter permanently in place. Scratches or other damage to the front element of your lens are a major expense, but a UV filter is (relatively) cheap to replace. Any other filter can then be placed on top of the UV.

Thank you all so much for taking the time to respond. I am a teacher and just got back into school, so I haven't had a chance to respond to your answers. Thanks so much!
