> Regarding Software Updates from Apple: I have a look at what they are, and know that some of them don't apply to me. So I uncheck them. Next time I run Software Update, there they still are, eager to be downloaded.
You've misinterpreted the checked boxes; they mean "Install" now, and unchecking them merely delays installation.
Select any d/l's you don't want to be offered again, click on SU > Menu Bar > Update > Ignore Update, click on "OK" in the dialog box with which you'll be presented, and you'll see them again only if you click on either SU > Menu Bar > SU > Reset Ignored Updates or on "Reset Ignored Updates" in an SU dialog box.
