You don't need yum to install the ntfs module rpm if that is all you need. Yum is a tool used to check the rpmdatabase and compare to set repositories to see if rpm packages are newer and installable.
Fisrt you need to know the kernel version you have. Use the command ' uname -r '
Now goto
http://www.atrpms.net/ and look under the FC4 > NTFS section and get the one that matches kernel version.
Download it.
Now open a terminal session and su to root.
Goto the location you saved the file too.
To test run the command ' rpm -ivh ntfs*.rpm --test '
If no errors or complaints then run it again minus the --test option.
Not sure if a reboot will be required so the system will recognise the new module.

Also I would do a little research into rpm and it usage to understand it with the usage with Redhat and Redhat Clone distros like FC.
