Lol, its all good with that trinket.
What I can see though is you should replace your off hand with Ward of the Violet Citadel
. Its from badges so run a couple heroics and you're golden. That'll help with your hit rating and allow you to drop some of the hit gems.
Also, enchant your chest with 8 or 10 stats whichever is easiest for you to afford. You'll want 23 haste to your cloak but it's not the most imperative thing at the moment.
For your trinket here are some viable alternatives that aren't too terribly hard to get. Titan Forged Rune of Accuracy
and Battle Master's Accuracy
. Yes both are from pvp but thats going to free up quite a bit of hit rating so you can gem more spell power or haste.
The rest really will just come with general upgrades from raiding. You're on track.
As for this, make sure you have squawkandawe downloaded and running that will help you track your eclipse and if you don't have it now, you're going to see a nice increase in your dps.
Other than all this, find a practice dummy and go to town. Don't clip your dots, don't clip eclipse. Profit from practice.
