I'd just make your own. Download the addons from curse. Get in game and set it up. I know it takes a while, but when your done you know where everything is and how to fix it on patch day when Blizz screws em up. Some suggestions for you.
Aloft-awesome mob health bars
Pitbull-makes your char, pet, and other bars uber customizable.
Omen-need to know how much threat u are producing
SBF-buff frames galore, adjust em how you like and where you like.
Graphpaper-helps you line up your UI real neat, get rid of it when done

Recount-mines always closed during fights. I can see how well we did after the boss is dead.
CBH_Viewport-I love this mod, but its up to you. keeps my frames off my screen.
There are many more add-ons out there. Use what you like, you can always delete the ones you hate.
