1) You can best travel to Interlaken via the Brünig Pass and Meiringen: that's a great scenic route. From Interlaken, you can head for the Jungfraujoch. Please enter your trip in the timetable
for details on all available connections and routes. You better not purchase your Jungfraujoch tickets in advance, as the trip is highly weather dependent. Buying on the spot shortly before taking off is a better option. You will be able to do so at the Lucerne railway station upon showing your Swiss Half Fare Card. You'll have to specify the route in advance. From Interlaken, it's nice to make a round trip, getting up via Lauterbrunnen/Wengen and down via Grindelwald.
2) The trip goes via Engelberg. The timetable
will give further details (enter 'Kleintitlis' as your destination).
3) Suggestions are a boat trip over the lake, a visit to viewing points Pilatus and/or Rigi and (in bad weather) the Traffic Museum or Glacier Garden.
4) You do need a valid Swiss Half Fare Card
in order to get a discounted ticket from the Swiss border to Zurich. I assume that the leg from Salzburg to the Swiss border is for free, if you have a valid Austria Pass. In most cases you can easily activate the Swiss Half Fare Card yourself by simply writing down the first date you need it, or it's already activated with the first travel date printed on it. If you let me know your country of residence, I can provide a direct purchase link
