The items in your Start Menu are made up of the shortcuts in two folders: by default these will be

c:\documents and settings\YOURUSERNAME\Start Menu

and

c:\documents and settings\all users\Start Menu

Ensure all the programs you want hidden have their shortcuts only in YOURUSERNAME\Start Menu, and other users will not see them. Also change folder permissions as suggested above to restrict access to your Party, Stars etc directories under c:\Program Files\... to your account only.
