Depends on what you plan to use the re-saved images for.

Doesn't matter.  These options only affect the display of partially
loaded JPEG content as they are being downloaded to your browser.
Once completely loaded, the JPEG looks the same.

There is no "one size fits all".  You have to play with the numbers
until you find a setting that looks "good enough" for your uses.

I'd make *copies* of the entire folder.

: and Bob's birthday archive? That would mean and making lots of folders - but
: it does seem to solve my problem of keeping the separated...

For every event, mark one folder as the "raw archive" containing all
photos straight from the digital camera without any alterations done
(no resizing, no cropping, no color correction, no Photoshop tweaking,
etc., you get the idea).  Then make a separate folder containing those
photos that you want to display, containing copies of the photos you
have chosen from the archive folder.  It's easy, it's friendly to most
slide-show applications.  Worried about disk space?  Get a new hard
drive or burn the photos to a blank CD or DVD.
