It looks like you've got the information you need.... but I thought I'd let you know about these two useful web sites if you should ever find yourself in the same situation again:
www.toandfromtheairport.com
- as the name suggests, tells you about public transport to and from airports all over the world
www.bahn.de
- the web site of Deutsche Bahn, the German national railway company. This lists ALL public transport connections in Germany, not just trains, and you can search on street names
