Hi Bob and welcome to MySwissAlps!
You have made the right choice I think in taking trains everywhere - everything in Switzerland is accessible by train or bus, but not by car.
As for rail passes, a Swiss Travel Pass would work for you very well. Your son qualifies for a discounted "youth" Swiss Travel Pass as well.
You can read about all the major attractions that are covered (or partially covered) by the Swiss Travel Pass here - and there is also a handy map as well.
As for your itinerary: If you mountains, hiking and smaller Swiss villages I would give Zurich a pass and go straight to Luzern (local German spelling for your first 2 nights). Have a look here for attractions to see around Luzern.
Interlaken is a nice town as it has very good rail access - from here you can visit Grindelwald, Thun and other Swiss towns like Lauterbrunnen and Murren. Interlaken itself isn't the prettiest town and I often mention to people you may like to stay in one of the smaller villages instead. Have a look at the links for the towns above what to do there and where to stay.
I hope that helps start your planning, let us know if you have further questions!
