I made a very plain login page with a central logo, and a few links to login/register & recover password. Thought it was simple and keeps the riffraff out of the main site.
Firstly make backups of the files that are being replaced so you can revert back if you don't like it!
Edit the index.htm page with your site details , and copy it to /www
Upload nzedblogo.png to /www/themes_shared/images , you can use your own image which you will need to rename.
Upload the .tpl files to the frontend folder of your theme. I'm using alpha theme.
Upload the .php files to /www/pages ,and overwrite the originals.
Open Admin Panel/Edit-site and change Default Home Page: to /index.php
Thats it really !
