Camera fixed on tripod, controlled lighting, stationary subject with lots of fine detail and a distant background. Figure out which aperture is sharpest, which has the most pleasing bokeh, etc. With the amount of depth of field you have, your primary consideration should be how it renders the image overall, not insignificant differences in depth of field.
I'd share my conclusions, but my S3IS got stolen before I knew to do this sort of thing. 1c. Regardless, opening up a stop for a lower ISO would've been a better call.
2a. Screens are great to focus with, are you kidding me? Hugely magnified focusing spot. Granted, the way the S3IS makes you use that button on the side would make it hard to use while holding it in front of oneself, but... 2b. Doing self portraits? Hold it to your eye, focus on your hand, nudge it a little to compensate for the lens being slightly forward of your eye. On a tripod? Stand where you'll be standing, focus on the tripod head. 2c. Don't worry about hitting the eye exactly so much. Hitting your forehead is better than hitting a wall, and these small sensors have enough depth of field even at f/2.8 to cover focusing slop in these situations.
