Polarizing Filters

You'll need to get one that fits your biggest lens (largest filter ring) and step-up rings for the rest. I'd also suggest some kind of screw-on hood for the filter, since you won't be able to use any screw on hoods for your smaller glass.
You should also consider some neutral density filters, as a really bright day can give you fits with a DSLR.
I've used some really cheap screw-ons for Canon video and after the compression and aliasing saw no difference in sharpness; when you can afford a matte box, it's pretty great to have though.

what Michael Carter said, plus: also take vignetting and polarizing issues when choosing the size of your filter...
say you work with these lenses:
tokina 11-16 f/2.8 (77mm)
tamron 17-50 f/2.8 (67mm)
canon 50mm f/1.8 (52mm)
a 77mm filter will work on all of them (with step-up rings), but only if you don't use the tokina near the 11mm end, because there you'll get vignetting
to minimize this, you could go for a 86mm filter, but it's not worth it, because actually you don't want to put a polarizer on a 11mm lens (usually), as it will create weird images (light coming from one side of the picture is coming at an angle that's too different from that of light coming from the other side of the picture, thus the polarizing effect is very different, and you get weird images, say with sky that's blue in the center but white in the corners, or things like that)
maybe all this won't matter to you, depending on which particular lenses you use
