You are in your fury gear so it would be nice if you got on in your tanking gear or linked a character developer with your prot gear. Basically for your gemming gem all stamina unless the socket bonus is 9 stamina or higher in that case put in a hybrid stamina gem.
Don't worry about expertise you shouldn't be having threat problems and if you are it is most likely because of a wrong rotation. For your Emblem of Frost gear since you didn't link your armory it is hard to tell but a general way to do it is
1. Offset Belt
4. Offset Chest
5. T10 Shoulders
6. T10 Helm
7. Crafted Legs
8. Crafted Boots
The T10 gloves are a really bad pick as your first choise since the offset gloves are miles better and if you are going for the two piece the shoulders and helm are the best designed since they don't have any offset or crafted emblem pieces that are clearly better.
