Here are my two cents worth of advice:
I will occasionally place a drop of oil on the ejector rod (not on the ejector star) and will put a dab of grease on the yoke shaft. Key word is a drop- as the ad slogan goes, a little dab'll do ya...... Work the ejector rod and spin the cylinder a few times, then wipe off any visible excess. Most problems that people seem to have with revolvers are due to over-lubrication. Mix oil, heat, spent powder, and lead --- and you can get a gooey sludge that expands beneath the star and pushes it rearward. Then the cylinder gets stuck. Very small amounts probably won't be a problem, but lots of folks overdo it.
If I am removing the sideplate for some other reason, I will place a drop of oil on the bottom of the rebound slide and on the hammer and trigger pivot pins. However, I believe that S&W revolver lockwork was designed to work with minimal lubrication, and that excess oil will just attract dirt and eventually gum up the works. For that reason, I advise against blindly squirting oil into the hammer recess, around the trigger, etc.
Also, any oil that goes into revolver lockwork should be the kind that will never dry up and leave varnish; you should use high-quality synthetics and avoid cheap generic products like WD-40 or 3-in-One.
