Was wondering if you could make an outlined list of which addons that you're using are hosted on which sites. I use 2 addon updaters (Curse, and WoWMatrix), and about a third of the addons in your pack either aren't recognized by curse (hosted elsewhere), or aren't supported by wowmatrix (not released with a GPL), or both. A breakdown of which ones can be found where would be much appreciated (plugin bundle download links would be the shizz).
Although I use a 1440x900 window for WoW, I'm pretty sure I can trim enough from the borders to get a clean look. Sharing my UI SS once I am comfortable using it. Doubt mine will ever match the quality of your epic naxx screen cap :-)
PS: Used my updaters to update as much as I can so I don't have to deal with an endless string of API errors. Gonna try out the UI tonight and tinker with it, hoping my updates didn't screw anything up.
