No I hasn't been able to update to any newer versions of Poser yet (I hope to get Poser 2012 sometime soon) but for right now I own Poser 7, lol... I'm way behind, but it works good for me and I've been waiting for them to come out with the next best Poser before I give up P7 cause I think P7 is one of the best versions... so no IDL yet, lol...

It does have IBL tho, lol on one light I think the rest are just normal point lights, 2 specular lights, 1 shadow light, 1 IBL light and 1 diffuse light (give or take one, lol I can't remember the exact settings right now but this sounds pretty close)...

As far as the gems go I might have to re-model them, even though I turned "Smooth Polygons" off for the hairband it still seems to be a lot smoother than when I modeled it so it could be the shape of the gems, I don't know tho...
