My .htaccess file re-directed problems?

Question

Update: I have updated the file, I did comment that I was getting a 500 server error, but I don't know if that is was just a passing thing or if something in my .htaccess messed things up! Anyway this is the file I am now using and this works, by that no more 500 error but still will not keep me on my localhost, vaio-server but keeps transferring me to my live site!

Any Ideas?? Please??

 DirectoryIndex index.php index.html

 # Upload sizes
 php_value upload_max_filesize 25M
 php_value post_max_size 25M
 # Avoid folder listings
 Options -Indexes

<IfModule mod_rewrite.c>
  # Redirect everyone but from visualhouse office
  Options +FollowSymlinks
  RewriteEngine on
  RewriteBase /

  # Maintenance
  #RewriteCond %{REQUEST_URI} !/maintenance.html$
  #RewriteCond %{REMOTE_ADDR} !(^127\.0\.1\.1)
  #RewriteRule $ /maintenance.html [R=302,L]

  #Redirects to www
  RewriteCond %{HTTP_HOST} !^vaio-server [NC]
  #RewriteCond %{HTTPS}s ^on(s)|off
      #RewriteCond %{REMOTE_ADDR} 127\.0\.1\.1 
  RewriteRule ^(.*)$ http://vaio-server/$1 [R=301,QSA,L]

  #Empty string
  #RewriteCond %{REMOTE_ADDR} (^127\.0\.1\.1)
  RewriteRule    ^$ app/webroot/    [L]
  #RewriteCond %{REMOTE_ADDR} (^127\.0\.1\.1)
  RewriteRule    (.*) app/webroot/$1 [L]
</IfModule>

I am hoping you can help me! Below is my .htaccess files for my Apache server running on top of Ubuntu server. This is my local server which I installed so I can develop my site on this instead of using my live site! However i have all my files and the database on my localhost now but each time I access my server, vaio-server (its a sony laptop), it just takes me to my live site! Now eveything is in the root of Apache, /var/www - its the only site I will develop on this system so I don't need to config this to look at any many than this one site!

I think thats all, all the Apache files, site-available/default ect are as standard. - Please Help!!

Many Thanks

Glenn Curtis.
