I wouldn't bother with any of this. The effects on the SSD are too low to be worth it and there is no discussion on the tradeoffs that are being taken. Disabling hibernation is really a shame for one. Trim is done excessively and the benefit is not that big. The weekly trim should suffice and no need to do it on boot.

I also doubt the disk scheduler is of any importance, as long as there are enough IOs in the queue in the disk it will be fast, otherwise it will not. All schedulers will allow multiple IOs in the queue for all I know.

I do the noatime for any system without regard if it is an SSD or HDD. I just don't use atime at all to bother about the extra work needed to maintain it.
