You have two choices, install with the installer script which will require compiling a kernel interface (it does this for you but you need your system setup correctly) or you can use an RPM that is available for you already.
If you install by the installer you'll need your kernel-source package installed, matching your current kernel. You'll also need to use this command line before running the installer.
If you use the RPM this should be taken care of for you, but you might still need the kernel-source package installed. You will have to configure the driver and your X setup in either case, so you need to read the nVidia readme on how that is done. Pay special attention to the section on 'editing your XF86Config' which is a file in /etc/X11.
