My first trip to Switzerland. Very nervous

Good day! I have quite a fewquestions hence I posted them under miscellaneous. Thank you very much fortaking your time to read through them. It's my first trip to Switzerland, I've self studied through several websites over the past 2 weeks, however got a little confused after all the "holiday homework". I'm pretty nervous, do help me through my questions. Appreciated much!

[u]Swiss[/u][u] Pass[/u][u](2 for 1)[/u]
1) Iam a Singaporean, studying in Switzerland,am I entitled to buy Swiss Pass (2 for 1)?
2) Isswiss pass (2 for 1) cheaper when bought at Zurich Airportas compare to eg. Lucern train station?
3) Mustboth travelers be present during purchasing of swiss pass(2 for 1)?
4) Isthere any limitation to how many times one traveler can purchase the swiss pass(2 for 1)?
5) Whatis the difference between swiss pass and swiss card?

[u]1 day travel passes[/u]
1) Does 1 day travel pass valid on all transports in Switzerland?

[u]Railway[/u]
1) isit safe to purchase train tickets from zurichairport/ train station on the day of arrival in switzerland to travel to lucern?(will there be incidents where the train does not have vacant seats?)

[u]Mobile Plans[/u]
1) Arethere any good and cheap temporary/short (say for 3 weeks) mobile plans fortourists (or foreign students studying in Switzerland) which include internetconnection (data plans), cheap incoming/outgoing calls & SMSes?

[u]Tickets[/u]
1) Weare visiting several places in Switzerland.Was wondering if it is necessary to pre book the tickets?

[u]Advise on my itinerary[/u]
1) We are studying at IMI(Kastanienbaum – Luzern). We areplanning to visit several places in Switzerland during our 1 weekholiday. (Mount Pilatus, Rigi, Jungfraujoch, Stanserhorn, Mounttitlis, LakeLucerne and Zermatt).Could you advise us on how should we go about planning the route so that wecould visit all in 1 week?

2) As for Zermatt, Iunderstand that we have to travel via Glacier Express. How do we travel fromLucern to take the glacier express? If we have swiss pass, do we still have topay the tickets/ reservation? I saw onGlacier Express Website that Reservation fee
during Summer is 33 CHF, and Winter 13 CHF. Is that a 2 wayfee or a 1 way fee?

3) Base on the places that we planned to visit, itis advisable that we purchase the 2 for 1 swiss pass or the half fare swisspass?

For Emergency:

Is there any important/ emergency numbers we should take note of during our tour?

Another few questions that pop into my mind. i've tried tosearch on the ways to go to all the places i mentioned above from Lucerne train stations(from sbb website) but it doesnt seems to work. Therefore, would appreciateyour help in guiding us. Please Correct me if I’m wrong.
