3d vrporn sucks unfortunately. Best cooms are in VRC playing multiplayer coom. 

As for care; lenses are sensitive, use only very soft cloth. No direct sunlight.
As for cables, yes they will go bad over a time, but valve will replace your cable if the headset is in warranty with not too much hassle. Out of warranty... wait for stock I guess. I'd check for stock now and then so you have a spare for when warranty ends.
