I would suggest forgetting the filters until you identify a specific need. I got one set for a superzoom that i have, but find myself not using them at all. On an Ultra wide angle zoom i have, i use a uv filter to avoid damage to the lens, and on a DA 300 i use a UV filter for protection, but on the rest, none.
On an ultra wide angle lenses, a CP filter can give changes in the saturation across the sky due to the varying angle at which the sunlight is striking the surface. Also, on the typical zoom, the 2 stop loss of light can make a sig difference in the morning and evening. I'd rather have more shutter speed or more DOF than the polarizer.
As for water flows, you can need those ND filters during daylight hours to get those creamy affects, unless you use blended images such as the Multi epxosure feature on the K10 and K20 or in PP software.
Circular ND graduated filters, yes i bought one, that fit the lens threads are more trouble than they are worth in my experience. better the square ND graduated filters that have a bracket to hold them. with those you can vary where the horizon is.
In general, i think one is better off initially putting money into pp software, than into filters, at least i the ones i bought spend most of their time sitting unused. One of my friends asked me why when he visits the areas i photograph, they don't look nearly as good in real life :-) Well, it isn't because of filters, i can tell you that ;)
