Oh, that bend is heartbreaking. Short boxes and backing boards are a solid start, but for a collection your size, I'd go a step further. Get some dividers to separate runs or alphabetize them, and always store the boxes on their long side. That keeps the weight even and prevents those spine creases. It takes a bit more time to set up, but it saves so much grief later.

My buddy works in Tucson and just uses a standard power stretcher. Is the heat really THAT much worse in Phoenix?

I totally get being upset about the "starter home" thing. My aunt said something similar about our condo. I just told her straight up, "This isn't a starter for us, it's the finish line we worked for." Setting that boundary right away really helped.

You can try using clear scotch tape on the shiny side, but it might get stuck in the player again...

Doubt it's that serious...
