Definitely get EZDome and then go here for some great hdr light sets. EZDome reads the .ibl file included in these and sets up the lighting for you as well. And you can download their program sIBL Edit to even make your own sets from other .hdrs. Some of the best are freely given away at https://hdrihaven.com/. Also, do yourself a favour and sign up at the SmithMicro Poser forums. I was a latecomer to P11 as well and those forums have been the greatest resource for knowledge as people had been posting there since P11 came out and most everything's covered.
