Since the guitar notes (on the staff) and the guitar notes on the tab should
be the same notes, you shouldn't enter them twice.

It would be better to define a variable guitarNotes:

      guitarNotes = relative c {
        g'4\3 g\3 g\3 g\3
      }

This will create two problems:
1.  You don't want to have string numbers show up on your guitar notes
(maybe)
2.  The guitar notes are an octave lower than they're usually written in  a
treble clef

We'll fix both of those problems below.

To eliminate the string numbers, we have two choices:  we can eliminate the
New_fingering_engraver, which creates string numbers and fingering
indications:

          \new Staff \with {remove New_fingering_engraver} {

or we can leave the engraver there, and just turn off the string numbers by
setting the stencil to false:

>           \new Staff {
              \override StringNumber #'stencil = ##f

To fix the problem of the notes appearing in the wrong place on the treble
staff, we change the clef, as shown in the Notation Reference section 2.4.2:

              \clef "treble_8"

Here, we just use guitarNotes:

              \guitarNotes
>           }
>           \new TabStaff {

And we can just use guitarNotes in the TabStaff, too:

              \guitarNotes

Now that we have predefined fret diagrams, you should plan on *always* using
the FretBoards context.  The only time you should ever use a markup fret
diagram is if you want to use it in a markup for another reason.

So at the top of your file, put the line:

\include "predefined-guitar-fretboards.ly"

Then define a variable that holds the chords to be played:

myChords = \chordmode {
  g1
}

And change your overall structure to

\score {
  <<
    \new FretBoards {
      \myChords
    }
    \new Staff {
      \new Voice {
         *melody goes here
      }
    }
    \new StaffGroup <<
      \new Staff {
        *guitar music goes here
      }
      \new TabStaff {
        *guitar music goes here, too
      }
    >>
  >>
}

This should resolve all of your problems, I think.

HTH,

Carl
