Agree on the jewelry fixes, those should be your top priority. Get the rest of your sigs of learning so you can put most (and later all) points into vitality. Perhaps switch out the jewels in your weapon and belt, the ones you have now aren't doing enough for you. Get the rest of your lvl 125 charms and maybe even some lvl 130 ones if you can get some in a trade or something. Lastly see about getting a Shamanka on switch to cast bloodlust and boost your damage a bit.
And later, down the road see if you can get a hold of Black Masquerade, Spirit Walker and The Collector. Maybe even The Angiris Star. But those are all a bit costly and you can make due without them for now. But when you can get them they will be very helpful.
Good luck, and have fun
