Armor: While you are still a fighter, use Warrior armor. The speed increase of hunter armor is not going to be worth it most of the time. If you happen to get R2 hunter armor, you might want to use it for running into a dungeon since that will boost your speed; however, once you are where-ever it is you are running in to, change back to warrior armor.
Tip: Before doing the job change to archer, up your rank 3 warrior armor to rappelz-item.com/tag/level/">level 10. You can then use it as your pet's armor. You may actually want to level several rank 3 pieces of armor for this reason. Before doing this, you should check prices of warrior armor in the auction house. Sometimes people are just trying to raise money and you can purchase pre-leveled equipment there for less. This also applies to the equipment you will need to buy as you hit rank boundaries.
