1) As of 6/27/2014, the sets have been named Light Nadhin, Medium Nadhin, and Heavy Nadhin.
2) Right now, these are the skins for the level 100 essence (slottable) gear. Don't know about essences yet? Follow the link provided.
3) As of 6/27/2014, these CAN be dyed. (Woohoo!)
4) The head, shoulders, and boots cost 10 Silver Tokens of Dol Amroth and 10 Golden Tokens of Dol Amroth apiece. The chest, legs, and hands cost 20 Silver Tokens of Dol Amroth and 20 Golden Tokens of Dol Amroth apiece.
I do not know if we'll be getting new skins for the class specific gear, but they're currently using the same undyeable skins as the Erebor armor sets. I suspect that this will not change. However, enjoy the screenshots!
