My and many other people usual advice with any creaking in strip, clean re grease, reassemble which you seem to know jugging by your link in your op.
The non drive side b.b cup sticking out suggest to me that if you have no wobbling on the bottom bracket (you don't mention any) and the non drive side cup is tight that you are running a b.b for a 73 mm shell in a 68 mm shell. If it's out by about 5mm chances are that is your answer. If it's a shimano sealed b.b if you take it out is will have a sticker on it telling you the details of the b.b.
