Having UK residence visa has no effect on whether you need or not need Schengen visa. Switzerland is now part of the Schengen zone and is implementing the Schengen visa system. Your nationality (or your citizenship) determines whether you need Schengen visa to travel to Switzerland. See the Related links for a list of countries whose nationals are required to have Schengen visa when traveling to Switzerland.
Whether you require a visa to travel to Switzerland depends on your nationality. Citizens of EU and other Schengen countries can travel to Switzerland with no restrictions. Citizens of many other countries automatically get a 90 day entrance when they arrive. Other citizens need a visa, which is normally granted for 90 days.

Not if you are a citizen of an EU or Schengen Area country which issues national identity cards, then you can enter Switzerland using that identity card. Otherwise you need a passport. If you are entering Switzerland via the land borders there are not normally any passport / ID card checks, as Switzerland and all countries bordering it are members of the Schengen Area. But you still need to carry your passport or ID card as this is a legal requirement in Switzerland, and you might be unlucky and get asked to show it at the border.
It depends on your nationality. Switzerland is part of the Schengen Area. If you have an EU or Schengen area passport, there is no minimum validity. You can even travel to Switzerland on your national identity card, if you are from a country that issues them. If you are from a non-Schengen/EU country you need a validity of at least 3 months on your passport, and if you need a visa then you also need 2 blank pages on your passport.
The difference between the two is that, a travel agency is the place or company that arranges the travels that people need while the travel agent is the specific person that arranges the travel is the travel agency.
