Congrats on getting TWRP installed! The rest is easy.
In TWRP select 'Install' and navigate to wherever you have the zip file with the bootloader/TWRP package, select it (if it has xxx signed.zip in the file name you need to check the "verify zip signature" option. sbdags usually signs his zips - don't know if he did with this one).
Swipe the button to flash the file.
When it finished, boot back to system. Do not flash a rom at this point! That would cancel the bootloader flash. Boot back into system first, then back into TWRP and then flash the rom.
BTW - flashing the modified Asus stock rom is perfectly fine, but I wonder why you don't flash CROMi-X 5.2.2?
That rom is from the same developer, based on this stock rom and miles improved since sbdags debloated the stock version.
sbdags stock rom is not really supported whereas he puts out a better version of CROMi-X about every 10 days! It's exhausting to keep up! LOL

You can still flash the BL/TWRP package you downloaded already. It's the same as the one for CROMi-X.
