Is there any way of modifying the preamble, so instead of typing
$\mathtt{x}$ ...
\begin{eqnarray}
\mathtt{y} & \mathtt{=} & \mathtt{z^\pi}
\end{eqnarray}
I can omit the \mathtt{...} commands?

You can add
\everymath{\mathtt{\xdef\tmp{\fam\the\fam\relax}\aftergroup\tmp}}
to the document preamble (or the part of the document where you need this)
and
\everydisplay{\mathtt{\xdef\tmp{\fam\the\fam\relax}\aftergroup\tmp}}
if you need display math as well.
In then in addition you may need to force the initialisation by putting
\setbox0\hbox{$ $}
in the preamble otherwise the first expression may not be initialised correctly. This just makes an empty math expression on a box and discards it to avoid the problem.
\everymathcommand, and also eqnarray-vs-align for reasons to avoideqnarray– cmhughes Jul 11 '12 at 16:46
