[S&L] [NenaUI] Help needed :D

The top bar is the Order Hall Command Bar. You can disable that in the General section of the ElvUI config.

The vertical frames are not nameplates but unitframes. They are used in NenaUI and I don't know if you can use the regular unitframes instead. Look for an option to disable them somewhere in a UnitFrames section of the NenaUI settings.
