Hi there
Most questions have been answered. As to the insurance: I would recommend the Mobiliar (Schweizerische Mobiliar). Starting prices are not the lowest, but they already include a lot in the basic packages (assistance etc). If you take what's included and how much others charge for the same they are a good deal. Plus they tend not to make a big fuzz if you need them. By my experience they pay damages without much quarrel and very promptly.
Also they have a very speedy assistance covering Austria as well. Might come in handy- given where you live and all...
Same goes for axa-winterthur. Actually I think most insurance companies in Switzerland are quite good...
