I am no expert at fury, my warrior only just dinged 70, but from what i understand, dps spreadsheets are not to be trusted, but you are right, strength is a better stat than hit, but there is no point in stacking strength gems if you are no where near the cap. Also expertise is of equal value to hit up to the point where it is capped, which is 6.5% to avoid dodges, the fact that u get 2% from talents and another 1.25% if u have a racial means you don't need that much.
Key points being, get to soft cap, then stack strength with some expertise and keep crit above 35% full raid buffed and you will be doing pretty good dps.
