Actually, all the stems should have the same thickness.  I think this is a
problem with your pdf previewer, not a problem with the actual output.  I
think that if you use Acrobat Reader to print the pdf, your stems will all
be the same size.

Why do you want to make the stem lengths shorter?  Stem lengths are
calculated automatically by the layout engine to be consistent with standard
layout.

You can  shorten the stems by setting the stem-shorten element of the
details property for the Stem.

This has been discussed on the user list in the past:

\override Voice.NoteHead #'font-size = #2
(but see below for more detail on this).

As far as I know, it isn't possible to center the score systems.  But I may
be wrong on this.

Here's an example that shows how different staves can be set to different
sizes.

#(define Ez_numbers_engraver
   (list
    (cons 'acknowledgers
          (list
           (cons 'note-head-interface
                 (lambda (engraver grob source-engraver)
                   (let* ((context (ly:translator-context engraver))
                          (tonic-pitch (ly:context-property context 'tonic))
                          (tonic-name (ly:pitch-notename tonic-pitch))
                          (grob-pitch
                           (ly:event-property (event-cause grob) 'pitch))
                          (grob-name (ly:pitch-notename grob-pitch))
                          (delta (modulo (- grob-name tonic-name) 7))
                          (note-names
                           (make-vector 7 (number->string (1+ delta)))))
                     (ly:grob-set-property! grob 'note-names
note-names))))))))

I don't understand this.  Bar 9 has only half notes.  What do you want with
the beams?

Add a new value for tagline to the header.  See
