Sounds good. To the RAM, as long as it's 8GB 1600 with a voltage of 1.65v or less you're good. Brand loyalty on RAM really isn't a huge deal anymore as it usually just all simply "works" these days.
Long as it's a Force GS or Force 3 you're good to go. Good stuff still, and comparable to the Force GT in terms of performance too.
You honestly shouldn't need to touch the bios. I just (two nights ago) built an i3 3220 / ASRock B75 based rig and it booted straight into my flash drive to install the OS. I'm willing to bet on first boot up it will boot to any bootable media to install Windows be it flash drive or DVD.
The only drivers you should need are on the ASRock website. Find your specific motherboard manual and download INF/Ethernet drivers. You shouldn't need anything else. Then head to the Nvidia website and download the latest WHQL drivers for your video card. Do not use drivers or software on the discs that come with the hardware.
As to setup, the only thing you should need to do on first startup after Windows install is go to this guide to properly setup your OS for the SSD use.
SSD Tweak Guide
Ignore the utility part. Also while you're in the services menu disable:
Microsoft Shadow Copy Provider
Volume Shadow Copy services
Once you do that, install said drivers ^^ and you should be ready to pwn some noobs with your new machine.
