I'm not sure where those holes are that you reference in your note-they don't sound familiar. As a general rule, here's what I do for slot machine oiling and maintenance. Mating surfaces that rub each other/rotate should be oiled if they start to stick. Grease can be used on heavier wearing parts/bushings, but I try to use as little grease as possible, and instead use 3 in 1 oil, as grease can collect dirt, especially if exposed to the air. I usually use grease where oil would run away in use. Don't use oil around any part that contacts the coins, such as the coin tube and payout slides.
The Mead and Geddes repair book says to oil and grease it every 6 months, but I only do it every few years.
