OMEGAKAI - If youre loading a rom(not from backup) you will always want to wipe your temp files in recovery before loading the rom. To answer your question about the gapps zip, yeah, if you want those apps, youre going to need to flash that after the rom. JUST BE SURE, you dont restart after flashing the rom zip. You need to flash that gapps zip right after you load the rom, BEFORE YOU RESTART. Hope this helps!
