This seems to solve all the problems, and I don't even need to go out and buy any kit either. It even sorts out the power level issues that Smarty kindly pointed out. However, what I'm not sure about is the function of the TV/data Isolators - do I need one local to each appliance (TV or computer)?

Yes, that should be fine.
So long as you have an isolator between anything in your house and the outside network, then that is OK. So fit the isolator in the outside box and then split the feed from that to your TV / Modem. Your signal levels then will be little different to what you have now.
There is a lot of information on the forums about isolators and how they are there to protect against lightning etc. This is not the reason for them! Lightning would not care if you had an isolator or not - it can easily jump that small distance across the isolator. The reason they are fitted is to ensure that any fault that might develop on your STB or the interconnects to it, does not mean that dangerous voltages are sent back up the network. They are also a help when fault-finding as there is no DC path through any customer equipment from outside the house.
