According to my research, most experienced bears (and tanks in general, actually) are saying not even to bother gearing for hit, just take what's naturally occurring on gear. My bear is simply an alt and hasn't done any raiding yet, so I can't say how that feels with my personal play style just yet.
Fluid Death is a nice trinket you might want to go for if you feel squeamish about not gearing for Hit, plus the 380 stacking Agi is delicious for both survivability and threat. Mystile recommended this trinket a few posts above me, and I'd agree.
