5 day trip to Switzerland

Hi, my wife and I will be visiting Switzerland for a period of 5 days from 19th May to 23rd May and then travelling onward to Vienna.
I intend to buy the 4 day Swiss Flexi pass for my stay in Switzerland and also avail of the current 2 for 1 offer. I have a couple of queries which I am hoping that you could address. Thanks in advance.
Will be arriving in Zurich on the 19th of May and moving on to Geneva on the same day. Will my Swiss Flexi pass cover the trip to Geneva?
On the 20th we will be taking a day trip to JungFrau. I expect the route to be from Geneva to Interlaken and then onward to Jungfrau. What part of this journey would be free (covered by my swiss pass) and what would be the cost involved for the balance of the journey (return)
On the 21st we will be taking a day trip to Zermatt. I expect the route from Geneva to be via Visp. Again what part of this journey would be free (covered by the Swiss pass) and what would be the cost involved for the "non-free" part of the journey.
On the 22nd we plan to take a day trip to Annecy by bus. This will be the day that we wont be using our pass.
23rd May - we have a 10am flight to board from Zurich. We plan to take the morning train from Geneva to Zurich. Is this doable or would you suggest that we reach Zurich a night before ie the 22nd?

Thanks.

Hello,
the map that you attached was most helpful. Perusing through the same I gather that the return journey from Zurich to Geneva as well as the trip from Geneva to Zermatt would be covered by the Swiss Flexi Pass. I would however appreciate it if you could confirm the same for me.
Cheers!
