Focal distance is distance btw camera and subject. Different from focal length. But focal length also affects DoF. Keep aperture and focal distance constant, and change focal length: you'll get different DoFs.

Wide open, focus peaking is very nice to have, but x5 magnification (MF assist) makes MF possible even without peaking. NX20 has the focus bar instead of peaking, though.
