Your gems, enchants and talents are all good. You've got enough expertise and hit to be at the soft cap, and the two blues you have are better than any epics you could easily get to replace them.
You're doing it right. Only thing I would suggest would be to replace your Dodge/Stamina gems with Defense/Stamina gems where you won't lose a socket bonus or your meta by doing so. It'd be a slight increase to your avoidance because your diminishing returns would be spread out over four stats, rather than just Dodge. You're absolutely fine as you are, though, and I doubt you'd notice a difference if you did make this change.
