</table>and remove it to get rid of the SMF header.
Then find{SYS_MENU}<br />{SUB_MENU}and replace with{SYS_MENU}{SUB_MENU}to get the menu into one line.
However, all you have left is pretty much looking like the classic theme, so I don't understand why you're going though all this - the whole point of the SMF theme is to make your coppermine gallery match the looks of your SMF board. Removing the key tokens, there's very little left of the original look.
