Here is one way to label the curves:

plot[\[Tau]_, \[CapitalOmega]_] :=
Module[{arg, abs}, {arg, abs} =
Abs}[(1 + I*2*\[CapitalOmega])/(1 +
{arg/Degree, 20*Log10[abs]}]

\[Tau]list = {7, 8, 9, 10, 11, 12, 13, 14, 15};

txtlist =
Table[plot[\[Tau], \[CapitalOmega]], {\[Tau], \[Tau]list}] /. \
\[CapitalOmega] -> -0.52;

Table[plot[\[Tau], \[CapitalOmega]], {\[Tau], \[Tau]list}], {\
\[CapitalOmega], -0.5, -0.01}, AspectRatio -> 1,
GridLines -> Automatic, GridLinesStyle -> Dashed,
ImageSize -> Large],
Text[\[Tau]list[[ii]], txtlist[[ii]]], {ii,
1, \[Tau]list // Length}]]]

I am not sure what exactly you want to do with the grid but you can specify your own regular or irregular grid using the option GridLines. See the examples in documentation.
