What about (a) doing a search and (b) reviewing the German Railways thread in the European Railways Forum?

And (c) nothing is easier than taking that train: You follow the signs to the "Fernbahnhof" (long distance railway station) or "Sheraton Hotel", both are clearly signposted, follow the long walkway and arrive at the station. it takes me 10 minutes from the luggage area to the train. You have to schlepp your luggage, on board of the train it should not be a problem. For all further queries please consult the thread mentioned.
