I know it's not exactly the point, but would you mind sharing what specific mic and headphones you went with for this? It can help to get a sense of what to look for to create a similar setup.
I have the mic on an arm to cut down on bumps and typing transmitting through the desk, but I find it doesn't have to be right in my face. I have it above the monitor, out of view of the camera. YMMV depending on room echo, my walls are bookshelves which is pretty good as treatment.
