  1. instead of the 550, get a 5770/6770, they are cheaper, perform the same and use less power. For the psu get a 500w+ unit from Antec, Corsair, Seasonic, XFX, OCZ or PC power and cooling. Dont go with unknown brands unless you find a good proper review of it.
  2. You can always get an accurate read on how much PSU power you need by inputting your current or future hardware into the PSU calculator at the link below.

  3. Yep, 500 would be plenty. You could run on an Antec 380, but it wouldn't be efficient, as PSUs lose efficiency toward the top of their load capacities.
