Chest, shoulders, and helm are all pretty much BiS fully upgraded. The only real choice is between gloves and pants, and you seem to have made it already. Toravon will drop pants too, so get the chest, cross fingers for the pants to drop, then maybe work around.
I wouldn't hold out for Toravon to drop your tier pieces. Theres a 1/20 or so chance of your item dropping, and thats not even counting the pvp items. Instead, go buy your tier pieces when you need them, but save token upgrades for those that can't drop in VoA: Helmet, chest and shoulders. So even if you spend emblems on 251 gear, you may upgrade it to 264, which is still much better than holding back and messing up your gearing.
