First thing to realise is that you can change the "density" of the  
notes with the command/property

    \override SpacingSpanner #'base-shortest-duration

as seen in the following snippet:

%%%%%%%%%%%%%%%%%%%%%%
\version "2.11.41"\include "english.ly"
\paper { ragged-right = ##t }

theMusic = \relative
{
        c4 d8 e f4 g8 a |
        bf4 af8 gf f4 ef8 df |
        c1
}

\score
{
        \theMusic
}

\score
{
        \theMusic
        \layout
        {
                \context
                {
                        \Score
			\override SpacingSpanner #'base-shortest-duration = #(ly:make- 
moment 1 12)
                }
        }
}

\score
{
        \theMusic
        \layout
        {
                \context
                {
                        \Score
			\override SpacingSpanner #'base-shortest-duration = #(ly:make- 
moment 1 24)
                }
        }
}
%%%%%%%%%%%%%%%%%%%

I also find Lilypond's default spacing to be (slightly) too cramped  
for my taste -- I increase the default spacing in almost every score.

> > not necessarily have the line breaks in the same places

It may be that the spacing issue is the only one you need to fix --  
i.e., once you increase the default spacing, Lily might just produce  
"perfect" scores for all versions (i.e., score and parts)!  =)

If not, you will need to define manual breaks (as suggested, e.g., by  
Mark). However, I recommend that you keep the break definition  
OUTSIDE of the music content -- after all, breaks are strictly  
"presentation", and thus should be separate from content. [The #'tag  
construct is a useful one, but it encourages mixing content with  
presentation, which is not always desirable in the long run; in  
particular, if you choose to define line breaks "per edition", your  
music can quickly become cluttered with more #'tag elements than  
actual notes!]

An example of what I'm suggesting is included below -- hope it helps!
Kieren.
