Regarding payout requests on the ICO site, just to be sure I understand correctly:
If I want to transfer my KMD balance to a exchange, I need to enter the KMD wallet address I got from the exchange in the field "Enter KMD Address" and confirm to change the KMD address. Then I go to the "PAYOUT" page and request the payout.
Maybe this sounds obvious (I know) but it's better to ask...
