Day 2: You have quite a marathon in mind! I have been to both Junfraujoch and Schilthorn, and have following remark. Going to the Jungfraujoch means going above 3000 m above sea level. Unless you live in Peru, this will be a unique experience for you, and a strain on your body (thin air) because of the quick difference in elevation if you arrive from Interlaken. My advice is you spend two hours there, so that you can enjoy the place in no hurry. You might keep better memories if you go either the Jungraujoch or to Schilthorn, but not both on the same day. Schilthorn is a bit, not much, less high than Jungfraujoch. There is not much to do up there so I can't advise you to stay two hours, but still relax, maybe have lunch up there. Also mind that these rides are not cheap!
Second Day 3 (presumably Day 4!) You could do the Harder Kulm hike you initially had in mind, or go to Trummelbach Falls. Interlaken is a good base, but the town itself is not exceptional.
I don't know about your tastes, maybe you like riding trains. If I were you I would skip the Golden Pass and Montreux, and go directly from Interlaken to Zurich Airport, but have a long stopover in Bern. The city is quite charming. In the old town all sidewalks are under galleries, so that sightseeing there is fine even if the weather is lousy.
