Need advice regarding my July trip

Hello,

We are a couple arriving and departing Switzerland through Zurich Airport on 04-Jul morning and 09-Jul evening. Here's what we have thought -
04-Jul: Arrive Zurich in the morning, take a train to Lucerne, local trips in the city, overnight at Lucerne
05-Jul: Trip to Glacier 3000, local trips in the city, overnight at Lucerne
06-Jul: Round trip Golden Pass, trip to Jungfraujoch, local trips in the city, overnight at Lucerne
07-Jul: To Zermatt, local sights, local trips in the city, overnight at Zermatt
08-Jul: Take Glacier Express to Chur, local trips in the city, overnight at Chur
09-Jul: To Zurich, local trips in the city, fly out in the evening

1. Is the above tour a realistic one, or have we packed too much into it? Please feel free to suggest alternatives, this is just a thought of packing whatever we can in 5 days.
2. Which ticket / pass should we buy - saver pass / card / half fare card?

Thank you,
