Yeah, I always tape a full center line and full 1/4 lines, and if it is a kids show on a large stage I will do full 1/8 lines (like for Nutcracker) but usuallly i just do a small mark at the downstage and upstage edges for 1/8s.
Then at c/c I tape a large bright colored X (usually pink or yello). I do the "white line of death" at the edge of the marley, and also white tape around any booms or offstage obstacles that dancers might run into as they're running offstage looking into bright sidelight (like FX machines or scenery that has to store in the wings).
The final marks I do are Xs or dashes on and around any "stage hazards." We played on one stage that has a trap that is warped out of the rest of the stage, so there was this raised lip -- I put marks around something like that, or a white X over any divets that are in the stage so a dancer knows not to plant their pirouette right there.
And of course, spikes for any scenery or props or furniture, or any specials that the dancers might need to be in.
