I recommend that you install the latest stable LilyPond version 2.10 from
www.lilypond.org -> Downloads. There's an installation package there that
works for all Linux distributions.

I made a quick hack to solve a similar problem in

You may want to adjust some parameters, for example replacing -2.8 by 0
or whatever. If you want parenthesis and not brackets, you can use a similar
strategy, for example by defining

rightParenthesis = {
\once \override BreathingSign #'text = \markup{ \fontsize #4 ) }
\once \override BreathingSign #'Y-offset = ##f
\breathe
}

In order to be able to use these commands in a ChordNames context, you have
to add the engraver that handles breathing signs (since I use the 
breathing sign
mechanism above), i.e. you have to add the lines
\layout{
 \context{
   \ChordNames
   \consists "Breathing_sign_engraver"
 }
}
to your file (for example at the very top or the very bottom of the file).

Not if you want it fully automated. However, you can turn of the clef 
symbol
using
\override Score.Clef #'break-visibility = #all-invisible
and turn it on again using
\revert Score.Clef #'break-visibility
so if you manually specify the page breaks using \pageBreak, it's easy
to insert these commands at the appropriate places. For key signatures, just
use KeySignature instead of Clef.
