This script will help you optimize your gear for the PVP mini-games. There are options to buy cheap(configurable, default 1k) mall gear that is better than what you have, and give a comprehensive list of the best gear in-game with wiki links to research how to acquire it.
Configuration for the script can be seen typing zlib pvp in the GCLI.
