why not just ask about the design you intend to do
instead of all these questions?
allow 6 mm between mains and low voltage
use Class 3 insulation
use metal earth screens
use double insulation
don’t run high a low voltages cables together
don’t run cables over sharp edges

put a certain amount of gaps for transporting high voltages through PCB. Alternatively, you may use a separate shielded cable for wiring that carries high voltage rather than running it through the circuits, just make sure the solders are done well, or electric jumps may occur around the soldering (if you’re soldering by hand, this is largely irrelevant if a machine does the soldering).
And please do your homework by your own.
