This explains how to update the bios and this thread has the address for the ftp where the new bios updates are kept. Problems I've had were mostly fixed when I eventually flashed up to 1.3. Whether your system will be stable with 4x1gb, I don't know. I went with 2x2gb so I had the option of adding another 4gb later. So far I've not had any hangs or instability with this setup.
The board has 6 SATA ports and 2 ESATA ports on the back, so you should have enough physical ports for your system. Setting up RAID didn't seem too difficult, you enable it in the bios and go on from there.
As for whether you'll see a difference between P35 and 680i, I don't know.
Hope this helps a little!
