First you will get maxed at 4000 honor. I have no idea what pvp gear you already have but so you know most people start by getting all the honor gear(season 9 stuff). By doing BH and getting conquest gear you should try and get all season 10 stuff including the weapon. Most people at this point already are all season 10 geared and only use honor to get enchanting matts. Season 11 is soon so if you are serious about pvp you should spend that honor on gear and grind out more honor.
