It's an interesting concept, but I think half the fun of the predator is simply not knowing what their society and world is like. That's what keeps the predators tantalizing to the fans, after all. If you knew everything the preds could throw at you, there really isn't much of a thrill left.
If humans were to go to a predator planet, I highly doubt it would be willingly. They would most likely be captured and transported there as potential hosts for a hunting queen, or if they would simply be intercepted if they ever tried to reach the planet by spaceship.
