Yeah flash the boot.img and go into the recovery
Make indeed a full wipe (wipe all you can except sdcard) so that means caches, data, system.....
Install the rom.zip and the installer will start. Make sure you choose the option "update only" and the full rom install. Nice choice you won't regret it.
I can also recommend some nice themes which you can find in my signature
And how about the recoveries, why do you sent those files? I'm using openrecovery-twrp-188.8.131.52-endeavoru, can I use it?
I'll try your themes, for sure!!!
