The spring loaded bearing reduces wear that would otherwise occur with the metal spring in direct contact with the plastic portion of the slide cover plate.
The channel liner prevents wear between the firing pin spring and the metal firing pin channel. More importantly, I would think the liner helps to keep the firing pin centered and lined up with the hole in the breech face and reduce risk of damaging the tip of the firing pin.
