Poser Pro Pack itself isnt any different to Poser 4 with regards to lighting, same set-up, same problems. The Python scripts however do make lighting a hell of a lot easier to experiment and manage. PC Bos, whos responsible for the enviroment stuff at DAZ did release some other lighting scripts which overlap these new ones and they are very useful for setting up and editing lights, and not only his own ones. The most useful is the delete lights, a godsend after loading a 30 light "global Illum" set-up. I do stills only and Ive not regretted getting Pro Pack and as more clever people release Python stuff it gets more useful. A few examples of scripts are a MAT file creator, a render script for rendering the seperate figures in a scene, a blink and twitch randomizer, a multiple prop copier etc. Pro Pack doesnt add a huge amount of functionality unless you are doing advanced stuff (Figure creation, high-end rendering) but I`m rich and stupid anyway, I hope you are too B)
