Thanks to all for their replies. If someone could simply tell me what the critical issues are and what changes need to be made, that would be great. Once again, this is how my .htaccess looks at the moment:

# disable directory browsing
Options -Indexes

# BEGIN WordPress

RewriteEngine on
RewriteBase /
RewriteCond $1 ^(index\.php)?$ [OR]
RewriteCond $1 \.(gif|jpg|css|js|ico)$ [NC,OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^(.*)$ - [S=1]
RewriteRule . /index.php [L]

# END Wordpress

# Add Proper MIME-Type for Favicon / gzip

AddType image/x-icon .ico
