The lines are the grey plastic flexable type lines. I know the braided stainless type you mean, they are not that type.
Is the balancing valve not in the replacable insert? I did reinstall it with a new one, but maybe I am wrong in assuming the balancing valve is in the insert.
I'd get a real plumber to do something with those lines you are talking about...
I'm about 99.99995% sure they do not belong inside a wall.
There are a couple of possibilities where the balancing mechanism would be depending on whether it is a Posi-Temp or, Moentrol mixer you have.
