Try this, I think it will speed things up for you.

-Take the default Poser lighting setup (You've got P4?)
-Change each of the lights to Spotlights (CTL-I)
-Create a cube default prop
-Parent each of the lights to this prop
-Set each light's Object/Point-At pulldown to this cube prop.
-set the cube prop to invisible

The Poser default lighting arrangement is really a textbook Lighting-101 set up. As such, it's not a bad place to start.
By using Spotlights with "Parent", & "Point-At" set to the cube prop, it allows you to rotate, translate, & scale all the lights together, while keeping them pointed at the same place, simply by adjusting the invisible prop. In turn the parent prop can itself be parented to get all the lights to follow a figure. Anyway, it'll keep everthing from going all wonky on you until you get a feel for the controls.
