You're UI will look just like this one for sure with some refinements.

Some of your elements (the mini-map to name one) need to be moved down so their butting up against the very edge of the your game window. That will also allow you to make the panel you have them all set against to be lowered in height by a small amount so it doesn't look like theres so much dead space on the bottom or the top.

Also depending on which frame your using to make that black panel you've got your addons sitting on (KgPanels or some viewport) you might want to think about messing with it to make it a somewhat transparent so you can see more of your screen without giving up that organized space. You'll also want to do this with your chat frame to make it mesh with it.

Speaking of your chat frame you'll want to probably make it so the boarder isn't on it so it doesn't stand out like it seems to at the moment, It will really tie the UI together better to have it that way.

Since It isn't in your picture I want to assume that Vuhdo fits into the space between recount and your mini-map, in which case I imagine it fits in that area ok but you might want to think of getting another unit frame mod to do something with your personal frame thats just chilling out on top. It might be a personal preference thing (specially on my part in saying something about it) but the basic WoW unit frame looks out of place with the rest of your UI.

As for the Buff question your not real clear about what your asking for or what it has to do with the UI featured here, because I dont see any thing like that in the screen shots of the featured UI. I assume you mean something to just move your buffs at all, like mentioned above, like Satrina Buff Frames or Buffalo 3. Of the two go with Satrina, its a much more robust and configurable buff frame mod.

Hope this helps
