I wouldn't worry so much about armor, but the HP is a bit low for starting Kara. You shouldn't be taking the brunt of damage, but you WILL take some, so you should have a bit more stam to deal with that. You won't do much DPS as a corpse. You definitely need to pick up a new MH hand though, that will be a huge detriment to your DPS. Hit rating can afford to slack a bit, you honestly have too much for your level of gearing. With precision, you only need 95 hit rating for yellow attacks to never miss on raid bosses, which is what you should aim for while bringing your other stats up. It's never a stat to ignore, but after 95 hit, crit is worth more as a result of flurry, and the fact that it applies to yellow damage while hit does not.
Bring your crit up to 25%, and your AP to around 1.4-1.5k unbuffed in battle and you'll be a lot better off. Don't bother gemming for hit, crit and STR will do you more good. STR is generally a better choice for gemming, but with how low your crit is, gemming for crit might not be a bad idea to get more flurry uptime, and as you approach 25%, start gemming away from crit and replacing it with STR gems.
You didn't ask for advice on spec, but if I MAY, possibly consider giving up imp. charge and 1/2 imp. OP. You won't be OPing much in a raid environment as most of your time will be spent in zerker for the extra AP, crit, and reduced threat. Drop 2 of those points into UW in the fury tree for extra rage gen, and 1 into imp. WW to make your BT/WW cycles more efficient.
You seem to be headed in the right direction, at the very least because you're concerned and asking questions. That's more than a lot will do. You're free to take the advice as you will. Comments anyone else?
