Dude, you really love polls. I answered 1,2,3, although looks are the least important factor for me. There are only a handful of woman here that I find so ugly that I can't watch their shows. The outfit isn't very important either. I also don't exactly know what you mean by "personality".
What counts for me are performance skills, interesting routines and overt eroticism/explicit content. The girls (and director) need to have a very developed sense of how to exploit their erotic potential- unfortunately, some are just clueless.
Nudity is a given minimum for all shows according to Totem. I believe the job of these girls is not to look or act cute, or just remove their clothes, but rather to aggressively flaunt their assets in a way that gets me turned on enough to throw virtual dollars at the screen, just like in a real strip club.
