I can't comment on your first question (which version is to be preferred).

You can make your code shorter by using \once :

{
  \once \hideNotes \grace d,8 \glissando <a' e'>2.
  \once \set glissandoMap = #'((0 . 0) (0 . 1))
  \once \hideNotes d,8 \glissando  <a' e'>2.
}

And for double glissando lines, \set glissandoMap is your friend. Each 
pair (x . y) in the list draws a glissando from the x-th note of the 
first chord (in your case, just one note) to the y-th note of the second 
chord.
