Great, that's just the kind of info I was looking for - ie, what stylesheets were available by default. I did discover via experimentation that 'pre class="brush: sql;" - presumably from the SyntaxHighlighter plugin - provides reasonable colours, but the indenting is slightly off with that one, so I'd prefer an alternative.
Your suggestion doesn't appear to be available - a pre block with that class simply appears as regular preformatted text with no syntax highlighting in my preview. I'm not much of an HTML guy, but I expect I can only use whichever stylesheets/plugins are made available by SSC directly, right? Since obviously the head element isn't made available by the blog editor.
