Yes. They will check your Schengen-Visa and passport and stamp it. Make sure you get the stamp! We had to many people telling they didn't get the entry stamp and had problems when they left the country.

Yes. The Swiss border controll will come on the train and check passports and your Swiss-Visa.

Not so sure but I think they will be Italian border controll officers on the train and do checks.
Enjoy your trip through Europe.
