Go do the Stockade and get the eyepatch from the quest in there, also you can pick up the Argas ring from the quest in Ashenvale. Get at least one Arena Grand Master trinket, and a PvP trinket.
Get stamina/agility enchants. +7 Stamina to bracer/boots are really cheap, +7 Agility to gloves is cheap. +100 Health to chest as well.
There are a bunch of other things you could go for, but take a lot of time and/or money. You can get everything I listed (minus the AGM(s) ) in under an hour with ~10g.
