erm⦠yeah the installation from ISO is easy but you have the POST-installation to worry about since you're basically booting into a highly insecure system.
being logged in as root is insecure, better to download sudo and be logged in as a user to minimize duration of being root
NO YOU DO NOT NEED THE AUR WHATSOEVER
getting to the point where you're able to use a desktop environment is difficult and takes a lot of time.
don't forget to configure your firewall, check systemctl for any failed services, check your logs and don't forget that pacman -Syu can send you back to tty.
plus more things I haven't mentioned, read post install recommendations or something.
