Your current gear should be good enough to enter a few Pug Karazhan raids if you are lucky. Many drops in Karazhan can easily upgrade your gear tremendously, even if your gear does not have the "Resilience" or "Stamina" that you may want it doesn't hurt to have epics to replace your greens and blues. Try to set aside a day each week to pve (such as Karazhan or Daily Heroics.
