I'm not sure about the source of these warnings, and I don't do any work
with the MIDI code, so I'm not sure exactly why the warning occurs.

It seems to work just fine to write your music all an octave lower (i.e. in
the sounding pitch, which you eventually get to by transposing) and put it
on a staff with a "treble_8" clef.

Using the treble_8 clef is the way to go.  But while we're at it, you create
a whole lot of unnecessary complexity in your file by adding unnecessary <<
>> and { } levels.

Here's what it looked like when I was done with it:

\version "2.13.10"
music = \relative c {
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
  \set TabStaff.minimumFret = #1 c
}

\score {
  <<
    \new Staff {
      \clef "treble_8"
      \music
    }
    \new TabStaff {
      \music
    }
  >>
}
\score {
  \music
  \midi {}
}
