Howto update Pure Nexus incl. Baseband, Bootloader + Backup Apps?

Hi,
after managing to unlock the bootloader, turning off the forced encryption and flashing Pure Nexus I am very happy to have a nice system.

However I am still on version 6.0.1-20151219 and I would like to test the newest version.

What is the best way to update to the newest version without loosing my apps? After doing some research (I am a noob) this strategy seems to be the best:

1) Do a complete nandroid backup over TWRP just in case of failure
2) Backup all user apps over Titanium Backup
3) Transfer backup folders of TWRP and Titanium Backup to my PC for later use
4) Download the newest shamu stock ROM from Google and extract it
5) Start my device in fastboot mode
6) Run

fastboot flash bootloader C:/image-shamu-XXXXXX/bootloader.img
fastboot reboot-bootloader
fastboot flash radio C:/image-shamu-XXXXXX/radio.img
fastboot reboot-bootloader

7) Start recovery (TWRP)
8) Do "Wipe data/factory data reset"
9) Flash newest Pure Nexus + gapps
10) Reboot
11) Configure phone (google apps etc.)
12) Install Titanium Backup, copy back backup folder and restore all apps
13) Done

Anything I missed or something wrong?

Thank you very much for your feedback!
