Good advice, Alex. My plan is to move everything that is even remotely delicate far away from where the installers will be. That said, they better be able to handle the carpet. This stuff cost enough that if they jack (ahem, f) anything up, I'll be calling the store right away.
On a related note, this carpet has a 120-day "beautiful" guarantee. It means that if I change my mind, for whatever reason, then they'll replace it for free. If I decide that I like a different color better - they'll replace it. Not the style that I want? Replaced. They'll only do it once for free, but it's a nice touch.
