Everyone should at least look at the Polish Genealogical Society of America website
www.pgsa.org. They have an annual conference near Chicago in the Fall. Plus there are regional chapters as well. I am a member and its a great organization.
Also check out a new site
www.moikrewni.pl on the bottom of this Polish website you can go to another page called Mapa Nazwisk (a surname mapping search engine) type in your surname, making sure that if diacritical marks are needed then they must be applied. Otherwise use their alphbet on the bottom of that page and search alphabetically. Each surname may have a masculine and feminine version and different possibilities with diacritical marks. but if you have that down, the maps are pretty cool and when you go over each potential location within Poland it provides a call-out of the area that you are over.
