You can not change the Starred functionality of your gmail account in the Mail app on Windows 8. Any of the starred options would need to be done on your Gmail account itself. Windows 8 mail allows you to see all of your email accounts in one place. But it
doesn't have the functionality of the gmail account options. It has the Starred folder and the email that is starred does show up in the Starred folder. But you can only make changes to the Starred email within gmail itself. Once you sync after making a change
in gmail, it does show up in Windows 8 mail.
