Listen to Eddie (also you were warned about the foam staining the concrete...). If that is your finished floor, what you should do is lay down Ramboard or masonite sheets, cover the floor wall to wall tightly - no gaps at seams, cut to fit, and then duct tape over all the seams. In fact you should have done that much earlier, especially before foaming, but that is in the past now. Don't finish the floor now!!! Cover and protect it.
Mine was covered with very heavy plastic (I think it was 8 or 10 mil) by the foam insulation crew and it stayed there on the concrete that was going to be stained until after drywall and painting was done, at which point the concrete stain was done. I did end up with a couple holes in it but nothing major and I patched things when I saw them come up. You have NO IDEA how much mud the drywallers will dump on that floor, and it will RUIN your finish. Trust me - they will make a gawdawful mess and will leave it to dry and you will have to scrape it off, and if your floor is finished it will trash it. You want to look at that the rest of your life knowing you could have avoided it?
You've talked about how inexperience had gotten you in a few cases, like the PEX line. You could have just laid down 2 PEX lines underslab instead of the white conduit/pipe and you would be already done. Live and learn. But when people tell you something like this - especially when they are standing up screaming it - use your head and listen to it.
Cover that floor tight and don't even THINK about taking it up until after drywall, paint and anything else major and messy is done.
