8 Day trip to Switzerland.. need your help.. plsss

Hey all.. how are you.. hope you're doing fine.. and congrats for having such a beautiful website.. its really informative.. :-)

Here's my query, I am planning a 8 day trip to swiss.. i am from india.. i have not been to Swiss ever.. so i need your help..

I am flying on april 19th 2012 to Zurich.. from zurich i go to Interlaken and stay there for 7 nights... and last night i stay back in Zurich..

I m buying a 8 day consecutive swiss pass..

Here's the thing.. i dont know how will i travel to different cities.. I want to cover Lucerne, Berne, Zurich, Interlaken, Montreaux, Zermatt. I also want to cover Mt. titlis, Harder kulm, Glacier 3000 and jungfraujoch

I just have a swiss pass.. is that sufficient ?? also please tell me if i can visit all the cities and Mt. titlis, Harder kulm, Glacier 3000 from Interlaken?? If yes, is it all connected by train/tram because i cannot afford private transport.. not even a taxi.. so will i be able to complete my whole trip only with a swiss pass?? or is there any place which i cannot visit without hiring a private taxi or something??

Or you can guide me on the following..
from interlaken hotel how do i reach:
- Mt. Titlis
- Jungfraujoch
- Harder kulm
- Glacier 3000
- Zurich
- Lucerne
- Berne
- Zermatt
- Montreaux.

Thank you in advance.. i hope my question is clear.. I await your reply very eagerly.. Thank you again. God bless you.
