Group Policy does not control that. You should use file and folder permissions to control that.

No this cannot be done - if users have the ability to read data then they have the right to copy it also.
Your only real solution to this is to use some form of Information Rights Management - but its tricky to set up http://www.microsoft.com/windowsserver2003/technologies/rightsmgmt/default.mspx
