Privilege - Pounds1230 with a London postcode and full NCP, Privilege have proved to be far the cheapest for me, I tried PO insurance they wanted Pounds2,000

Regarding tracker, PO dealer has suggested a new system that's has some big advantages over the current systems.
The big one as far I'm concerned is that you can actually contact your car by mobile and switch the engine off, Wow.

In the first instance the car calls you and allows you to locate the car and stop the theft

I've put a link for you all to see the products web site. The down side is it's about Pounds1,000 to buy, but the devise is transferable from car to car unlike all the current trackers.

Privilege will recognize the tracker supplied by i-mob (but you need to check for your own policies)
