Hi Steff,
I guess you want more system-system-spacing which is set in the \paper
block and not in a Staff context:
\paper {
system-system-spacing =
#'((basic-distance . 30)
(minimum-distance . 20)
(padding . 8)
(stretchability . 10))
}
The values are probably too large, just to show the effect.
This PDF shows which spacings have to be set in in which block:

Cheers,
Joram
PS: Your question showed me that the Lyrics and Chordname spacing is
missing from this PDF.
