This works for me:

Percb =  \new DrumStaff \with {
      \override StaffSymbol #'line-count = #1
  }
  {  \set Staff.instrumentName = "Percb     "
    c2 b a1
    \bar "|."
  }

You shouldn't try to put a new Staff inside a new Voice, that doesn't
make sense.

Not possible with this technique you are using:

  \new StaffGroup \keepWithTag #'score \music

where \music contains all the definitions including \new Staff etc.

The StaffGroup block puts a bracket over the new staves you declare
inside of it. Once you have put everything into a group, it's
impossible to put back some of them outside it.

Just open a new GrandStaff and put a pair of new staves inside it,
rounded by << >>

I think you should learn the use of \new in more deep, see
