    I think build quality is more important that the amount of fans, but if you want silence, one large fan will likely be quieter than two small fans. Two small fans may cool better however.

    Neither means anything. Even the 550W doesn't mean squat if we have no idea what brands are you comparing to. Are you able to provide links or the names of what you're trying to decide between? PSUs generally won't overheat if you have even just 1 fan, but again that statement is ambiguous because you provided next to nothing in terms of details.

    noise output is worthless if your system is overheating. I'll take a noisy system anyday over a hot one. Get a case with at least 2 or three fan slots. Use the bottom for intakes and the tops for outtakes for natural thermal flow.

    Those 2 power supplies are different. One is 24pin, the other is 20pin. If you are using a new P4 cpu, go with the 24pin board. If its an older system get the 20pin.
