Want to know how to see the space station? There lots of helpers out there. My current favorite is CalSky. I have set it up to give me email alerts for the space station, iridium flares and other cool things that are visible from my own back yard. Another site that you can configure for you own location is Heavens Above. I know that there are apps for mobile devices that will also do the trick, but I haven't explored that too closely.
Here's how the station looked earlier this evening from Tucson, Arizona:
