1. that is fine, the board will detect any pcie devices
2. no changes needed except see 3.
3. auto should be fine, this would detect a pcie express drive, if you are connecting a standard sata drive into one of these mentioned in 2. you could set this to disabled
4. disabled is usually default, this would be to save power during sleep or hibernation. best left at disabled to make sure you have no issues with video resuming from sleep etc.
5. I have never been in the Ez mode, I always hit F10 when exiting bios, hit save and exit to keep changed settings so I can assume yes
