New level 65 captain - what to focus on?

I hit level 65 last night and now am hoping for input on what to focus on to make myself more useful. My gear is mostly quest gear from the late-50s/early 60's with some level 58 crafted gear mixed in. My legendaries are both lvl 57 3rd agers. I am specced HoH right now with the LoC capstone trait...I have more class deeds to fulfill and of course I have uncapped traits right now.

So, what would stand me in the best stead? I'm not a min/maxer but I'd like to pull my weight in any instances, raids or other group situations.
