Honesty do what I did, Start adding and testing addons for yourself. See what fits for you. After a while your screen will look like a mangled horror of Vuhdo, bartender, recount, omen, quarts, and other things you will find necessary. Then all you have to do from there is get it organized and set to your liking. Then you will have built your own functional UI tailored to you and your play style.
No offense to any of the great addon packs out there, this is just my suggested and preferred method.
