-darkweave breaches is ok for hunter but leggings of the fang is preferable because darkweave give less stats (9agi>7int) and its cloth(it doesn't matter that much but a minor upgrade is a minor upgrade). If you want a different option, 5/5 falcon is a good piece (better for premades imo).
Hit is the most important stat for hunter. Many persons say they dont nottice the dps difference, (dps wise)the increasement isn't visible without testing it but its by far the best stat for hunter til you reach hit cap plus its not only about dps, hit also increase your reliability, like if your pet miss a stun on a healer or on the efc it can make you lose games ( happened to me many times before I realize how important hit cap is (its ridiculous losing game because of bad luck)(btw get hit capped, 8-9 hit is ok but hit cap is still the top priority, you wnat misses otu of the table).
also the herod shoulder are superior to shadowcraft one if you have access to BoA. However the rogue chest is superior to the hunter chest.
Idk whats your race but if your alliance in wsg you need 5% (4% if you are a draenei), and 7% in arena (6% if your a space goat) because there is many night elf and you dont want to miss them. if you r horde you should always have 7% (except if you know your not facing a night elf (you need 5% in that case)).
Someone suggested 5 hit rating to boot, its a good chant if you dont have access to boa but 7agi and getting hit capped via equipments and talent(if you can get hit cap with gear only its superior then talents) is better. Minor speed isn't as good as it used to be since we got cheetah now(it doesn't stack and cheetah if well used is really good (timing your aspect switch between attacks is very useful to get away(take some pratice tho)).
btw for pug you should use a set of gear balanced between agility and int ( I use a glass canon set here but if you are not a skilled hunter id suggest you to get some stam( but dont stack it like some huntards do).
for premade I believe that there is a post on twinkinfo for gearing a hunter for premade (on offense you want class canon set with alot of mana, if you play defense(idk if hunter are still viable on D(haven't premaded in a long time) stack stam and int).
as said earlie, careful aim is a mandatory talent, you can pick improved conc shot then 3 poitns in lethal shot(if you get hit capped via talent repalce lethal shot by focused aim) there is 2 points remaining, my preference would be savage strike but if your premading you might want to consider hawk eye or lethal shot.
hope my long post helped some, sorry about my grammar( second language)
