A little lube on the internal gears couldn't hurt. I don't think I would worry about the spray paint unless it starts to rub off and stain whatever you're cutting. A tune up should probably consist of adjustments to ensure the blade is parallel to the table guides, the fence is parallel to the blade, and the angle of the blade is accurate. If it works good and is adjusted properly, who cares what it looks like. Maybe a little wax on the table top to help wood slide easily would be nice.
And throat plates are often painted red to signify "danger zone".
