I just wrapped a gig shooting SD in 4:3. I just switched the camera back to 1920x1080, 30p. However, the cross hairs in the middle of the screen and the pillars on the ends that initially showed up when I entered 4:3 mode are still there. How do I turn them off?

I don't have the camera in front of me, but look thru the menu and "turn off" markers. It should have a sub menu for 4:3, turn that off.
