Using LyX I can add line numbers to my code listing. However, these are in the document (serif/Roman) font and look strange next to code blocks (Typewriter font). Is it possible to change the font of the line numbers to match that of the code block? Can this be achieved using either listing parameters or some LaTeX code in the preamble?

Program listings does not actually use the typewriter font family by default, so you have to change this in the settings. To change it for a single listing, right click it, choose Settings and select Typewriter as Font family.
To make it a global change, go to Document --> Settings --> Listings, and type in the following option:
basicstyle={\ttfamily}
For the spacing, try adding
columns=fullflexible
to the options list for listings. I'm not entirely sure about this, though the different choices for columns is described in the listings manual (listings is the package used for these program listings), section 2.10
Fixed and flexible columns.
A slightly different approach from Heiko's fine answer:
\documentclass{article}
\usepackage{xcolor}
\usepackage{listings}
\lstnewenvironment{bash}[1][]
{\lstset{language=C}\lstset{%
numbers=left,numberstyle=\normalsize,stepnumber=1,numbersep=5pt,
framesep=5pt,
basicstyle=\normalsize\ttfamily,
showstringspaces=false,
keywordstyle=\itshape\color{blue},
stringstyle=\color{maroon},
commentstyle=\color{black},
xleftmargin=5pt,
xrightmargin=5pt,
aboveskip=\bigskipamount,
belowskip=\bigskipamount,
backgroundcolor=\color{gray!20}, #1
}}
{}

%%% Always I forget this so I created some aliases
\def\ContinueLineNumber{\lstset{firstnumber=last}}
\def\StartLineAt#1{\lstset{firstnumber=#1}}
\let\numberLineAt\StartLineAt
\begin{document}
\begin{bash}[name=Test]
echo xyz
\end{bash}
\StartLineAt{30}
\begin{bash}[name=Test]
echo xyz
\end{bash}
\ContinueLineNumber
\begin{bash}[name=Test]
echo xyz
\end{bash}
\end{document}
The code offers two macros that I personally find convenient
\ContinueLineNumber
and
\StartLineAt
If you wouldn't like all your code to have consecutive numbering you might find it useful.
