Wordpress theme customisation and site help

General information for the website: Movie review website
Kind of development: Customization of existing website
Description of requirements/features: We have bought a new theme for our site that needs some customisation. We have the instructions on how to customise this, but it involves editing the CSS and we are not comfortable doing this. We can do all the customisation through the wordpress options ourselves.

We would also like someone to go through the plugins in our site, check that the plugins, the security and site is all working properly - a basic site MOT.
For someone who knows wordpress and understands CSS we don't see this taking more than a few hours. We have been quoted for this work outside of PPH but wanted to see the costs from freelancers rather than a company.

The site is www.welovemoviesmorethanyou.com
Extra notes:
We have just purchased a new template for it, and want the layout to be the same as the live demo version; http://livedemo00.template-help.com/wordpress_40114/ as far as the layout is concerned, slider, tab and widget area all need creating. The CSS changes that need to be made are all in the instructions at file:///Users/Jllyfldrs/Downloads/template_40114_Vd06X9I84tq5MBSBATRI/documentation/Documentation%20(Installation%20and%20Editing).html

This is only the home page we need setting up. We will do all the fonts and colours and categories etc. We will do all the customisation which is in the options within the theme settings in wordpress.
The main part of the instructions we don't understand are;

To make your WordPress look like our live demo please, follow the instructions bellow.

Install the template by following the directions
Then, copy and unzip files from the folder "plugins" to the /wp-content/plugins/ folder or use the admin panel Dashboard > Plugins > Add new > Upload and select your plugin.
Copy "uploads" folder to /wp-content folder.
Open the theme1695.sql file that is located in the sources folder with any text editor (preferably Dreamweaver or Notepad) and replace all instances of "your_website_url_here" with your website URL in the entire document using the Find and Replace tool (usually the Ctrl+H hot key). E.g.: http://www.mywebsite.com
Please, make sure that you do not have the forward slash "/" sign at the end of the address.
Save your changes and close the file.
Next, you can import the dump file with the phpMyAdmin tool or some other database management tool.

The main point is to get the home page to have the same layout as the demo version.
