they are referring to 6% hit from gear most likely (when you add 3% hit from precision you have 9-10% hit).
with lvling toons, i tend to just put talents towards one of the end-game builds (18/53/0 in fury's case) especially as a warrior since you can't heal so you have to have high dmg talents to increase your chance to live while questing.
even though at 80 arms is better dmg than fury at low gear lvls, fury is a better spec to level with due to increased rage gen and better multi-mob handling (through whirlwind and cleave).
would be good to change your glyphs since rending is considered an arms glyph (cant rend in zerker stance, which you will sit in alot as fury). get whirlwind to replace the rending glyph, and maybe execution or cleaving for your second, depending on if you pull alot of mobs at once or not.
