oh my gawd. I'll be in your same boat in a couple months. Am researching new liners and DREADING starting over with well water because I remember too well the coca cola brown stage and all the cleaning I had to do to get things in check: gallons and gallons of muriatic acid, etc.

I'm sure you've got this figured out by now, but curious how it went. My answer to you would have been to address the TA first because that will wreck your equipment in a heartbeat. It ruined our heater in a matter of two weeks before I knew what I was doing and the pool company was CLUELESS.
