Hi Max,
I found with my car that my UK insurance company would only insure it our here for 90 days. I had to transfer to Swiss insurance while still on UK plates (still am, actually). I wound up going with Zurich Connect, they were a lot more expensive than the others, but the only company who clearly said they'd insure a UK registered car.
As for the importing, a goold iste is the Swiss Customs one -

There's a form on there you need to fill in (

Then there's another 40CHF if you want to use the motorways. One tip I can deffinately give is not to try and do the importing at half 2 in the morning, when the customs guy on duty speaks less English than you do German and is half asleep!
One last gotcha that I got hit with - if you've owned the car for less than 6 months, you're probably best to wait till after u have owned it for more 6 months, as they could change you VAT on car otherwise.
Hope this helps
