Ok, now I have taken a clooser look at the interface you have selected in the screenshot: ArenUI 2.0 Silver Edition.
As far as I can see on the example image for the skin(http://www.lotrointerface.com/downloads/full203.jpg
) it actually looks like you got it all as it should be. With the minor exception that you have your quickbars docked (and thus they are floating a bit above the static quickslots) and not manually positioned as they are in the example image.
So I think you should try to undock all quickbars (under Settings / Quickslots, uncheck all "Dock bar x") and the try to align them as in the picture.
Hope that helps!
(if you get more difference with the other skin selected, post another screenshot with that too)
