Yes i know how to make a chardev but to be honest i haven't played feral since 2 years and i have no idea what stats I should go for.
for a pvp bear/FC you'll want agi, crit, and mastery
agility increases your crit (to proc savage defense more often), attack power (for bigger savage defense shields), and dodge
crit increases chance to proc SD
mastery increases the amount absorbed by SD
haste is pretty useless for a bear, so reforge out of that when possible. same goes for hit/exp for the most part
you could also gem for stamina, but since you'll have almost 120k selfbuffed it might be overkill. should be viable if you want to try it though
the downside to a bear is your absorb shield only works against physical damage, unlike a DKs blood shield. which is why i took talents to reduce magical damage taken, and use the meta gem to reduce it a bit more
you'll be able to put out a bit of offense in cat or bear, but keep in mind this is not a dps spec.
stat weights are a bit different for cats, but if you wanted to you could just respec and keep all the gear the same and do pretty well
