Really nice images Greg, especially for your first time out, we all overprocess when we start out
Based on the size of your Jupiter image (and your aperture and camera), I estimate you are imaging at about f/11.1 (or 3.8x the pixel size of your camera) which is pretty close to optimal.
The sharpening tool in AS!3 is only really meant to be an indicator, there are better programs out there for sharpening (Registax is the default standard, but Astra Image and a newish program called AstroSurface are also used).
Can you give more details of your capture process? Capture time, frame rates, that sort of thing? FireCapture records a logfile for every session, if you want post one of them, that would be helpful too.
