1. yes
2. Im not a big ASrock fan myself, Id get the Asus Z87-A
3. Is OK but the 850w XFX is cheaper and built By Seasonic
4. You could trim it up a bit, is blu ray necessary? You could also save a bit and get a 2Gb 770. The only reason I'd go with a 4Gb card is if you are planning on SLI and either triple monitors gaming or a 4k monitor. Also if you are not planning on SLI you could get a smaller PSU.
Made a couple of changes to your build.
