Answer 2

1. Make sure that your layers are inside the artboard, in rare cases sketch fails when pasting and arranging graphics into it.
2. Maybe you selected the background for export only. Make sure the "knife"-icon ist not marked on the background. Wrong example would look like this

Besides this you can export the iTunesArtboard to all needed sizes or following the shortcuts (⇧⌘A) for selecting all Artboards and open the export dialog with (⇧⌘E) provided by "nathan" :)

Answer 3

Select all artboards (⇧⌘A) and then Export (⇧⌘E) them.
