Have a look on here
http://www.meteorwatch.org Carl. They show meteors and ISS passes etc. to be honest it's not as hard as you think to photograph it. The website tells you what direction it comes above the horizon from and then it's all about having the camera set up to take some long exposures. Tripod, shutter release, patience and you should get there. Try also taking a few say 15 - 30 sec exposures and then merge into one photo to give a long trail. And also a good poi makes the photo even better.
Depending on the length of lens you have you can even get a pretty good close up image of the ISS as I have done before. I used my 150 - 500mm some major cropping and managed to come away with a shot that looked like something from star wars.
