Don't sweat what your gear is for now, once you hit the Outlands in a few levels all your gear will be replaced and you'll notice a nice jump in your HP quick quickly.
And don't stress your Sta to much, as a warrior you've other stats to worry about as well. STR and AGI for leveling. If you plan on tanking then you need to concern yourself with the Tanking stats, Block, dodge, parry, +def as well as STA
Not entirely sure of your exact spec but usually a nice 2 handed weapon is the weapon of Choice for Arms specced warriors.
