What are the best Professions for Pala?

I'm pretty new at the game, I got lvl 80 on this realm like 5 days ago, and I wanted to create a Human Retribution Paladin (PvP) I haven't even TOUCHED professions on my main account (which is Rogue) so I know nothing about them. So could someone recommend me 2 good professions for PvP retribution? I don't have to worry about gold because I'm gonna mail myself like 900 gold from my main.

If you are going PvP , its Jewelcrafting and Blacksmithing all day. Or you could swap Blacksmithing with Engineering.

Those 3 are the best PvP professions imo.

Mining/bs pve
Mining/eng or minjng/jc for pvp
Mining/enchanting for bloodelf paladins due to racial
