I recently did my fuel filter on my 04, very easy but got a huge shot of gas in the face. I even pulled the fuse for the pump, and let it run out but still had some pressure. Mine, you just take your thumb or a small screwdriver and push in these release clips and just pull the line off, and then to put them back on, you just slide the lines back on and they lock back in themselves. As for the bracket, its just a big metal clip, no nuts or bolts on the 04. Next time I might try and also release more pressure from the valve on the fuel rail.
