Is it worth putting some Hylomar on the bung threads
No, but it is worth replacing them with a metal equivalent.....which I assume is MHM B&Q reference.

Anywhere near 12 o'clock I have always placed my a 12, the jiggly thing is to allow any traped air in the system to escape as air rises to the highest point that's why it's at the top.. but you knew that
And there's me thinking the jiggle thingy is a hole to allow for a small bleed of water thro the thermostat disc so that the thermostat sensor is in a small flow of coolant and not in a stagnant pocket of coolant so that the sensor is able to sense the coolant temperature accurately and open as required.
It does bleed the air out as well.
