Technically, you're wrong. A sanding should be done prior to applying any coat, especially with a sheen like satin. Under the right lighting, a satin finish will highlight the smallest debris on a wall. From the can to the wall, and even some come out of the can with debris in it, the paint picks up dirt from the wall, fuzz from the cover, stuff from your shoe if you step over the pan (which you should never do), dust from the air after the paint is applied, etc. Without a sanding, by the time the second coat dries, you now have two layers of debris, rather than one. And now your wall will feel and might look like fine sandpaper. It's good practice to sand between coats, at least as high and low as you can reach standing.
To your question Bob, by the way how are you, I wouldn't use anything stronger than 150 or 180 on a satin. If the paper is too strong you could end up putting scratches in the first coat which might be visible after the second. 120 would be okay with a flat. That's for general sanding of the paint. For the spackle, lightly hit it with the 180 or use 220.
