That's a decent gear set for heroics but there are some definite improvements you can make to help you transition into epics. A couple of asides, false life is the only essential thing you're missing from your current gear set. You definitely want to have that. Also, forget about AC. It's essentially worthless in the current state of the game.
Here is the set I would be striving for:
Star of day, drow shortsword, or drow rapier
Black dragonhide armor (armor piercing 10, +5% damage for 30 seconds after a killing blow)
Resistance 6 goggles
PDK helm (con 7, str 2, intim 15)
Deadly 6 necklace
Pale green ioun stone (vitality 40, 5% xp)
Mithril cloak of the wolf (exc seeker 4, dodge 6)
Guardian's girdle (false life 40)
Guardian's ring (sheltering 24, yellow slot)
PDK gloves (str 7, con 2, 60 heal amp)
Sage's shoes if you can't get a pale green ioun stone (vitality 20)
Sage's ring (cha 8, potency 60, yellow slot)
War wizard's bracers (50 sp, 20 hp)
Elemental Fury is a decent weapon but Star of Day would be an improvement. The drow weapons are min level 21 but you can start looking for them on the auction or shard house now if you want.
bigdmag is right, something doesn't add up with your dodge. The parasitic breastplate has a max dex bonus (MDB) of 9 if I remember correctly. If you're following the enhancements as listed in the OP, then you get +12 MDB from swashbuckler cores and second skin. Because you listed your dodge chance max as 23%, I'm guessing you have the fencing master ship buff which grants +2 MDB and doge cap. So your MDB adds up. But your dodge (if following the OP) should be 19 from enhancements alone (cores, on your toes, and skirmisher), which brings it up to 25 with a +6 item, limited to 23 from your MDB. The black dragonhide armor has a MDB of 12, or 26 with the bonuses mentioned previously. It also has some nice offensive properties. The parasitic breastplate doesn't really do much for you at this point. If you don't already have the scales for a set of black dragon armor, keep an eye on the auction and shard house. Ingredients are pretty cheap these days.
The PDK helm and gloves will give you a total of 9 con, 9 str, and 60 heal amp. It's primarily the con and heal amp that your after from those.
Upgrade your necklace to a straight deadly +6 or better. Water breathing is only needed as a swap in item. Keep this, as well as your resistance item, upgraded to higher bonuses as you level.
The pale green ioun stone can be a bit of a pain to farm out, but is well worth it. You may also find one on the auction or shard house.
Get the Sage's shoes (from a Wheloon end reward) if you can't get a pale green ioun stone. You should have haste up all the time, so you don't really need striding in your gear set.
I would keep the Stormsinger's cloak as a swap item (assuming you can't find a higher perform item) for when you use fascinate. You don't really need a perform item for low blow and coup de grace. Their DC should be high enough without one. The mithral cloak of the wolf is a nice addition with both exc seeker 4 and dodge 6. It's fairly easy to farm the ingredients for the Eveningstar cloaks nowadays, and it shouldn't take you very long.
The Guardian's Girdle and Guardian's Ring are great defensive items.
Sage's ring for cha 8 and potency 60 should be self explanatory.
The War Wizard's Bracers are just another way to get a bit more hp.
The gloves, helm, and bracers are all Eveningstar commendation reward turn ins. You'll easily get all that you need by running chains 1-3. Just mention in group that you are looking for coms and most people will pass them to you. The belt, rings, and shoes are all guaranteed end rewards from Wheloon and Stormhorns quests, so you can even run them on casual and still get them.
That's roughly the gear set I would be striving for. It's all fairly easy to obtain and will provide a definite boost for you. It should add roughly 120 hp; improve your defenses through PRR, MRR, and doge; and improve your offenses as well.
Hope that helps.
