4 Wheel Disk Conversion; approx. cost?

Hey guys, I'm getting a parts list together for my hatch and am wondering what the approximate cost of doing a 4-Wheel Disk Conversion is? This link claims to be everything I need for the conversion does that seem right?

And also, this is reaal noob question but I was planning on getting rear lower control arms, will the Integra brakes fit on aftermarket civic control arms, or do i buy Integra control arms? Thx for all the help guys!
