Will I have to drain my system to replace the section of leaking pipe between the supply valve and what i think is a pressure reducing valve? And what is the red gizmoe after the PRV?

    is there a valve to the right if the two red valves? You need to isolate both sides.

    The red valve on the right is a pressure relief valve. If you have one on the boiler you do not need that

    You should however have a backflow preventer at the fill valve

    And if you do need to drain down, replace the relief valve on the boiler

    Buy a combination fill/ BFD

    if it is the relief valve there should not be a valve between it and the boiler.

    After you make that expensive repair and you still have the same problem, What will you check next?
