Save your money- get better at photoshop.

A circular polarizer is pretty much the only (hardware) filter I'd bother with.
The only other exception would be a quality UV filter. Though, I ran those primarily for the benefit of protecting the optics, and less for the UV (haze) reduction.
One caveat with a polarizer is that they can be hard (and sometimes impossible) to "tune" with digital cams that only have LCD screens, and not an actual (optical) viewfinder.
Also, keep in mind they can/will act as an ND filter in most cases as well.
As above, almost anything can be remedied in post, but it is nice to minimize your PS workload by getting good shots to begin with.
