the half moon looking scrape marks is what's called Oil Flaking.
the scrape marks are far below the machined surface to act as a reservoir for oil to collect and act as a bearing surface to reduce wear.
before reassembly it might be in your best interest to lightly stone the ways to remove any ridges where a tool or work may have dinged the ways.
the crater created by an impact of tool or work will slightly raise the metal from the newly formed crater that will interfere with a member sliding across the surface.
a fine oilstone ,fine diamond , fine ceramic stone with a little windex or mineral spirits will do a nice job.
personally i like the windex because it's effective and cheap- plus it smells a lot better too.
just be sure to wipe off any excess windex and lightly oil the surface as there is water present in windex and rust can occur easily
