Boomkin PVP (HELP with action bar/hotkey set up)

I just leveled my first druid to level 80, I'm going to PVP(mostly BG's) on him. Could anyone offer me some advice as far as action bar and hotkey set up goes. Any other advice is welcome as well. Wouldn't mind screenshots of your UI also.

Thanks you!

Here is my UI, I don't play currently but I might get back soon. And start filming some PVP videos. Link.
