Cheat for Final Fantasy IX

Hi...I am on Disc 4 and had a few questions.

Where is the birds-eye lagoon chicograph (#10)? It is ment to be west of eunorus plains qus marsh but I cant find a qus marsh that is on eunorus plains so far I have found 4 qus marshes.

I can't get to the treasure box on the second level in the windmill in dali I think it has the aries stellazzio in it.

How do you get the mayors key to open the door in the wind mill as I have not talked to him.

Thanks for any help anyone can give me. .
