No, newegg is just organized so well that people love them very much. Just make sure that you don't get used parts. They could obviously be broken in some way.
Either the Antec 902, or not mentioned there the HAF 922. It's cheaper, bigger and better than the 902.
As long it's a quality brand (OCZ, PCP&C, Antec, Corsair, SeaSonic) then 750W will be more than enough.
Have fun and good luck. Any other questions feel free to ask.
