The City of Tulsa website has a little web application -- you put in your address and it tells you your Council district and current councilor.
By the way, the maps in my entries on the Council race are scanned from the official map from the election board. (They sell copies of district maps, but they don't have them on the website yet.) The numbers are precinct numbers.
(I'm postdating this so it stays at the top of the blog through election day.)
