Does it matter whether I use the AF/MF switch on my Nikon D90 or on the lens?

On a Nikon D90 with an 18-105mm lens, is there any practical difference between switching autofocus on or off at the camera body versus using the AF/MF switch on the lens? Also, can it damage the camera or lens if one is set to autofocus and the other is set to manual focus?

There isn't.
Nope, it won't harm your gear - if either switch is set to off, your AF will be off.

For normal use, there’s no practical difference: if either the camera or the lens is set to manual focus, autofocus will be disabled. In other words, both need to be in AF for autofocus to work.
It also should not harm your equipment if one switch is set to AF and the other to MF. The result is simply that autofocus won’t engage unless both are set appropriately.
So, use whichever switch is more convenient for how you shoot.
