It's right in front of the fuel tank. Relieve the fuel pressure by removing the fuel pump relay/fuse or by triggering the fuel pump shut-off in the trunk. Start the car and let it die or crank it over a few times. Any brand but Fram is fine--I'd go with Ford. You'll also need a special tool that you can get from Autozone to remove the filter.
Block up the rear, put a rag around the hose you are going to remove, take off all the clamps and remove the hose. Make sure you are not directly under since fuel will drip. Installation is reverse and pretty easy.
