>dumdum question: if, in johnny's case, theres only 1 shoulder to put decals on, should i put the chapter icon or the squad role icon?
Because the left pauldron is covered in molecular bonding studs, the chapter icon would, in this case, go on the right pauldron. That was the "proper" way to do it back when your army consisted of plastic RTB-01s and whatever metal beekees you got from buying random blisters down at the FLGS.

That being said, combining chapter symbol with some other kind of markings is not out of the question, as shown in the First Edition Space Marine Painting Guide.

There's a rich tradition - especially in historical wargames - of trying to get the uniforms to look the way they should. Just because 40K takes place in the grim dark future of a fictionalized version of our own universe doesn't mean this tradition shouldn't apply.
