I'll give that idea a go.

I'm not so much wanting to apply their styles to my site, more a case of doing it the other way round and taking their design and layout and making changes to that. 

I basically want to be able to take a page and make a template of some sort out of it.

Managed to strip it back and get pretty much what I want out of the page.

Next question, the CSS file has all the styles on a single line with no line breaks (fail)

Is there any software or site that will auto-format a CSS file?

Google it first.... http://www.cleancss.com/

search & replace with regular expressions

Chrome's Sources tab in the Web Inspector has a { } button at the bottom that formats source files nicely - works for JS, CSS and HTML.
