2) For cleaning them, what sort of wipes could I use, to shift the odd spot here and there and deal with dust? I do not want to buy general ones, unless they are specifically non-offensive to such surfaces.
I use wipes similar to those without any issues, just make sure you are very gentle. I advise that you let the wipes dry a bit before you use them as they can cause a lot of smears on the screen.
For cleaning, I just use a microfibre cloth and some lcd tv cleaning solution, make sure the screen is cool to the touch first, I find if the screen is warm, it streaks.
As for the dust, just get a hepa air filter like iluvendo said.
