Using WordPress as a CMS – advice on doing it for localhost?

I have a plain-vanilla install of WordPress on localhost, virtual host in Apache set to:

127.0.0.1 myradiostationhere.com
127.0.0.1 www.myradioanytown.co.uk

and the virtual host works.

However, I don’t want to use it as a blog, but as a CMS like here:

http://www.brmb.co.uk/

and

http://www.brmb.co.uk/schedule/

(basically, any pages on that site are database-driven WordPress pages, not blogs).

I’m not asking how to create pages etc. – I understand that – but rather if anyone knows of the best way to do this.

I’m trying to emulate their look, but with similar CSS stylesheets, as per:

Fair dealing in a work for the purposes of private study or research (s. 29)

under Copyright, Design and Patents Act 1988 (that’s the legal bit out the way).

Would I need to edit the PHP files in order to get this to work in the way I intend to?

Anyone here had experience of custom WordPress CMS design/installs, and how would you recommend I go about this?

(note: This isn’t for a live radio station site, it’s a development/testing site on localhost!)
