Problem with lyrics placement (can't show lyrics below bass-staff)

[Mike Bosschaert]

Hi, 
I have a score with soprano, alto and bass music + lyrics. I try to get all 
lyrics below the staffs, but for some reason the lyrics are all shown between 
the staffs. I use Lilypond 2.0.3

My score section is given below.

Furthermore I would like to know if there is a way the avoid double rests 
(e.g. the soprano and alto part have common rests which are shown above 
eachother).
Also the stanza numbers do not show (music starts with 4 bars rests). Is there 
a way to get the stanza numbers at the beginning of the bar?

Many thanks for your attention and help!
