I think February can be lovely if you are not allergic to the cold! We went to Austria last Feb and it was great! Also have been to the Berner-Oberland in January and loved the winter walking in the mountains.
I think you have too many stops. And I hope those are NIGHTS not days! Interlaken is dull, so trade that for Muerren or Wengen as many recent posts have covered. Skip Zurich (it's just a city) and Zermatt (you do not have time), adding one more night to wherever you stay in the Berner Oberland and one more night to Paris. (We've also done Paris in off season and it's lovely.)
So consider:
Muerren or Wengen - 3 nights
Luzern - 2 nights
Paris - 4 nights
I don't see how you can fit in the Glacier Express, but you will have great mountain train experiences anyway. Going to the Jungfraujoch is a good reason to stay an extra night in Muerren or Wengen.
You cannot do all of this from one base so you need to stay in at least two places in Switzerland.
Please confirm you have 9 nights on the ground. It's your honeymoon! Don't make it a forced march. Once you nail down the itinerary we can discuss passes, but probably a Swiss Half-Fare Card will be the bet option.
