Hi!

Is there an option for the \showgrid command for showing only the line numbers (no lines) ?

no, but it's easy to add that option, 

put this in cont-new.tex (after \unprotect) 

\chardef\gridboxlinenomode\plusone
\chardef\gridboxlinemode  \plusone % 0:nothing 1:all 2:lines 3:frame

\def\gridboxvbox {\ifcase\gridboxlinemode\vbox\or\ruledvbox\or\vbox\or\ruledvbox\else\ruledvbox\fi}
\def\gridboxwidth{\ifcase\gridboxlinemode0\or.5\or.5\or0\else.5\fi\testrulewidth}

\def\setgridbox#1#2#3%
  {\setbox#1\gridboxvbox to #3 % given size
     {\forgetall
      \resetteststrut
      \offinterlineskip
      \hsize#2%
      \baselinerulefalse
      \gridboxvbox % calculated size
        {\getrawnoflines{#3}% \getnoflines{#3}%
         \vskip\topskip
         \vskip-\strutht
         \scratchdimen#2\advance\scratchdimen \lineheight
         \dorecurse\noflines
           {\strut
            \hskip-.5\lineheight
            \ifcase\gridboxlinenomode\or
              \rlap
                {\hskip.2\bodyfontsize\hskip\scratchdimen
                 \infofont\hbox to 1em{\hss\recurselevel}}%
            \or
              \llap
                {\infofont\hbox to 1em{\hss\recurselevel}%
                 \hskip.2\bodyfontsize}%
            \fi
            \vrule
              \!!height \gridboxwidth
              \!!depth  \gridboxwidth
              \!!width  \scratchdimen
            \par}}
      \vfill}}

\def\doshowgrid[#1]%
  {\chardef\showgridstate    \plusone % downward compatible default
   \chardef\gridboxlinemode  \plusone
   \chardef\gridboxlinenomode\plusone
   \processallactionsinset
     [#1]%
     [ \v!reset=>\chardef\showgridstate    \zerocount,
      \v!bottom=>\chardef\showgridstate    \plusone,
         \v!top=>\chardef\showgridstate    \plustwo,
        \v!none=>\chardef\gridboxlinemode  \zerocount,
         \v!all=>\chardef\gridboxlinemode  \plusone,
       \v!lines=>\chardef\gridboxlinemode  \plustwo,
       \v!frame=>\chardef\gridboxlinemode  \plusthree,
    \v!nonumber=>\chardef\gridboxlinenomode\zerocount,
       \v!right=>\chardef\gridboxlinenomode\plusone,
        \v!left=>\chardef\gridboxlinenomode\plustwo]}


now you can use keywords, like

\showgrid[lines.left]

\input tufte
