Parents renovating basement, all the walls are down, n exposed, Mother willing to wire for surround sound, need to know where to start n where to continue from there
Just get good quality wires that are rated to be installed behind the walls. Make sure that the audio wires are not running parallel and next to any power wires.
You could post this in the Homw Audio forums. Jan Vigne maybe able to answer this more comprehensively than I can. He tackled this issue sometime back.
