In my opinion, lose the 3/3 Eclipse and put it into 3/3 Celestial Focus. Personally the 3% haste is better than watching your procs like a hawk. I would give more reasons but there is a whole thread on Eclipse.
Also you'd probably want to lose Intensity just because you're mana regen is much like a pally now so you're crit rate is much more important to your mana regen. You could put that into Moonfury which is an increase in damage which is your ultimate goal as a boomkin.
Now, for pvp!
This is the build
I would use here.
Reason being is I found brambles is absolutely amazing now. I was watching my treants in pvp crit for 1000 on warriors. So imagine what it will do to those little annoying arcane mages. Imp Moonkin Form isn't particularily any good when all your pvp gear lacks spirit and the haste isnt that necessarily important to everyone, pvp is more about you than anything else.
Balance of Power and Moonfury is a must because it's an increase in damage and lessens the chance people can dispel your dots and you're getting 4% chance to hit w/o sacrificing gear and gems.
Pick up Eclipse because if you lead with Starfire and you proc off your wrath Eclipse you're going to be pushing out more damage.
If you do all of this, you're going to end up going 2/3 into Nature's Focus so you're pushback is going to be a little less but your damage output is much much higher.
Also, with 3/3 brambles watching rogues stun themselves to death is absolutely hilarious. Plus, your thorns will kick back decent amount of damage. With 1000 or so spell power mine will hit for roughly 170.
Thats my .02 cents!
Edit: Balance of Power is not Nature's Reach. Why I thought it gave range instead of lesser chance to dispel, who knows.
