Hi for cc you can have a notification email script and call that email script in notification

Script:

email.addAddress("cc", current.requested_for.email, current.requested_for);

syntax to call email script in Notification

 ${mail_script:script name}

For to address you can just add openedBY under who will receive tab under Users/Groups in fields
