Am I ready to root? topic

Hi!
I plan on rooting and installing Rayglobe Flex 4 and here's what I've done so far and what I plan on doing:

I've downloaded the following:

IOroot21.zip
LG_G2_Backup_EFS.zip
FreeGee
PhilzTouch 6.11.6
ADT
LGModemdrivers
Rayglobe flex 4

I intend on rooting, installing TWRP with freegee, backing up EFS and storing it in a safe place then install Philzrecovery, make a nandroid, then proceed to flashing rayglobe and dorimanx kernel.
Did I miss anything or is there anything I should be particularly careful wwith?
