Check the timetable link that I gave in my earlier post. Use the Swiss timetable from the SBB).
Trains over the Gotthard Pass route that proceed onward into Switzerland all stop at Arth-Goldau. Alternate trains go to either Luzern and on to Basel, or to Zürich. The train for the other of those two routes is waiting on the other side of the same platform...you might have to get off and walk across if the e one that you pick is going to Zürich.
However, all of that is clear in the SBB timetable. Just start from Como and go to Luzern. The SBB timetable will give you the fastest route.
