How to reproduce this?

[Carl-Henrik Buschmann]

Hi,

I'm a Lilypond newbie switching over from Sibelius. As part of my self tutoring 
I have tried my hand at reproducing a example (written in Sib) i used in my 
thesis:

I'm a bit stuck and i hope you guys can give me a nudge. 
This is my feeble attempt:

\version "2.18.2"
\language "german"

<<
\chords { 
  f2 gis4 dis b 
}

\relative c'' {
  \tuplet 3/2 { c8 c c }
  \tuplet 3/2 { c c c }
  \tuplet 3/2 { dis dis dis }
  \tuplet 3/2 { dis dis dis } | %m1
  fis4
}

\\
\relative c' {
  < f a c >2 < gis bis dis >4 < fisis ais dis > | %m1
  < fis b dis >4
}
\addlyrics { 
  V2 bVII III/IV I 
}
>>

Product:

I have many problems:

1) The chords are at the bottom.
2) The chords have the wrong font.
3) I have NO idea how to properly write roman numeral analysis, lyrics is not 
the way to go it seems.
4) The dottet phrasing line.
5) The 1. and 2. voice crash. 

Help?
