John,
It sounds like you have done a lot of good research and probably will be quite happy with your upcoming procedure. For the sake of accuracy I would like to refine a few of your comments.
You are correct in noting that pupil size is important, but not quite for the reason you stated. A slight increase in spherical aberration occurs after almost every Lasik procedure regardless of pupil size. Glare, halos and decreased contrast sensitivity are noted by a few patients, even those with small pupils. The problem with large pupils is that the optically-poor transition zone at the edge of the treated area is included within the pupillary aperture, analogous to non-aligned optics in a camera or enlarger (Trying to keep this thread somewhat photographic). Small pupils are better for many of the same reasons that smaller apertures make better photographic images.
The ability to focus at near after the procedure is very age- dependent. If you are older than say, 45 years, and if you have a perfect distance postop result, say 20/20 or better in both eyes, you will not, repeat not, be able to focus at 10 inches, or even 20 inches. If you are younger - yes, near vision can also be good, but even then you will lose it after a certain age.
