I always have a “global” voice that is used in every staff of the full 
score and the parts. You can put \time, \key, \tempo, \bar, \repeat 
volta, \alternative, \mark etc. into that voice and don’t need to repeat 
them in every instrument. Even \repeat volta and \alternative aren’t 
needed in the parts except if you want to use \unfoldRepeats for the midi:

%%%
global = { \repeat volta 2 { s1 } \alternative { { s } { s } } s }
violin = \relative { c'4 d e f g a b c g f e d c1 }
\new Staff << \global \violin >>
%%%

The basic structure of my projects is the following (files separated by 
%%%%%, I have some more files but they are irrelevant for your question):

%%%%%

global = { \time … \key … \tempo … s1*48 \mark \default … \bar "|." }

fluteI = \relative { … }
fluteII = \relative { … }
…
contrabass = \relative { … }

%%%%%

% full score:
\score {
  <<
    … full score with StaffGroups etc., one example staff:
    \new Staff \with { instrumentName = "Violin I" } <<
      \global
      \violinI
    >>
    …
  >>
}

%%%%%

… one book for every part:

\book { \bookOutputName "ViolinI"
  \score { << \global \violinI >> }
}

…

%%%%%
