Professions with MW Monk (PvP)?

Which professions should I go as a Mistweaver Monk and I will mainly PvP (random and rated battlegrounds)?

I currently have a 90 Holy Paladin with Jewelcrafting and Blacksmithing, a 90 Druid with barely any in Leatherworking and Enchanting, a 90 Priest with Enchanting and Tailoring, a 85 Shaman with nothing, and a 85 Death Knight with Mining.
