5 day N6 owner - my first monthly flash

Got my N6 from the Amazon sale. As the LMY48M factory image has just been posted, I want to make sure I do this right and not lose my data/settings since it's my first time.

Phone is XT1103. Unlocked 64 gig (non carrier/branded) but using a VZW Sim. Bootloader unlocked, rooted but still encrypted. Running TWRP-2.8.7.1. On LMY48I currently.

Are these the only commands I need to execute to update but not lose the data/settings (actual IMG file names taken from the 48M image)?

fastboot flash bootloader bootloader-shamu-moto-apq8084-71.10.img
fastboot flash radio radio-shamu-d4.0-9625-02.101.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot reboot-bootloader

Am I missing anything? I believe after I do this I will have lost root but I'll use CF-Root to get it back.

Thanks
