Um did you guys read the OP post? He said proffs from PvP perspective. Not a proff and gathering proff... He even posted he had the golds to spend to level it, instead of leveling a supporting proff.
Ok, Frozen Shadoweave set is a BOP Tailoring set. However, If your going to do alot of PVP, its kind of pointles to craft this set, as it has no resilience.
I believe, that anything else you might want from tailoring is BoE and you can get a tailor to craft it. (again, tho, you will prolly quickly replace anything with pvp rewards for the resilence)
Enchanting: I think for a lock, this is really a must have. simply because of the enchants, that you can only do to your own items ie rings. (its not that much damage but in pvp every scrap counts). This proffesion also allows you to make golds w/o a supporting Proffesion thru selling mats from disenchanting. You also get the occasional tip from someone for doing their enchants too.
Edit: You can also make Superior Wizard Oil witch is a nice +spl damage buff to weapon, that Persists thru Death.
Engineering: There is so much you can craft that is good in PvP, how can you not pick it? A well timed mortar, to stop a heal, a nice grenade into a group of enemies etc etc etc.. (again you prolly wont use the helm you can make, you will prolly get one with resilience, so you dont have to waste jem slots putting resil on it)--although the helm does kick ***.
JC: Dunno why you would consider this PvP wise. You can buy any jewel cut you want. Once you socket your PvP rewards, this proff has no bearing on PvP. Without mining to mine ores to prospect, you will still have to buy jewels to cut.
Alchemy: This can help by giving you cheap health/mana pots. Really tho, unless you make Flasks (wich are both guardian/battle and persist thru death) you will be burning lots of pots every bg, and at least 2 every arena.
Cooking: Definitely level this for Well Fed buffs. there are buffs for +spl damage, +30stam/spirit etc etc. You can also make golds off this, selling your foods you cook. (if you farm just about anything that drops meat/fish etc you can turn that previously trashed/vended food into quite a bit of golds)
So id say from a straight PVP perspective, assuming you got the cash to support leveling it, Engineering/Enchanting is your best bet.
