Apollo Twin with AutoTune for performance HELP

hey y'all.

live gear somewhat confuses me, but looking to get some assistance "for dummies" if you will lol. i'm basically trying to run autotune and some basic fx at my live shows with my apollo twin. I plan to use in-ears and run a wireless mic system too. so my question would be, what would be the easiest way to do all of this? is it smart to just get something like an XR12? can someone just break it down for me hahaha. will be running playback tracks as well.
