While I found most guitar specific points, I have problem with polyphony.

The "normal" polyphony gives a problem with tabs. The notes are 
written to the staff instead of tab. (see meaure 4). What's wrong?
The << {...} \\ {...} >> construct will always create Voice contexts,

you want new TabVoice contexts within your TabStaff. Please read "Explicitly
instantiating voices" in the manual for more information. One way to do 
it in your

score is

\version "2.11.25"

melody = \relative c {

\key d \major
\time 4/4

d8 a' d fis  a,, e' a cis | b, fis' b d  d,, fis' a cis |
g, d' g b  d,, fis' a d  | g,, g' b d  a, e' a cis |

\voiceTwo d,,2 a' }

secondvoice = \relative c {
 s1*4 \voiceOne
 fis'8 d, a' d   e a, cis e,
}

\score {
 <<
   \context Staff = Guit <<
 \clef "G_8"
 \new Voice \melody
 \new Voice \secondvoice
   >>
   \context TabStaff = Tab <<
 \set TabStaff.stringTunings = #'(4 -1 -5 -10 -15 -22)
 \new TabVoice \melody
 \new TabVoice \secondvoice
   >>
 >>
}



The bass notes in the first three measures (d, a, b, d, g, d, g, a) 
should be printed as half notes but stick with the beams. This is 
normally not correct but usual in guitar notation. How can this be done?

Certainly! If you define the macro
halfnote = {\once \override NoteHead #'duration-log = #1 }
at the top of your file, you can use it like
\halfnote d8 a' d fis  \halfnote a,, e' a cis |
