Hello Thomas,

I’m not familiar with this function, but I can help about the last two 
items:

Well, you could use two (manual) beams: { a[ b] c[ d] } – but I imagine 
that’s not what you intended. Colouring only part of a single beam is 
very difficult, I think, but with enough programming knowledge 
(virtually) everything is possible in Lilypond…

LedgerLineSpanner continues as long as StaffSymbol also continues, so 
you need the following:
{
  \once\hide Staff.BarLine \bar "|" % work around issue 3949
  \stopStaff
  % insert any tweak on LedgerLineSpanner here
  \startStaff
}
