Securing files

I decided to protect my wp-config.php (contains the database password) and my .htaccess by adding these lines in my .htaccess file:

< Files .htaccess >
Order allow,deny
Deny from all
< /Files >

< FilesMatch “wp-config.php[~]*” >
< Limit GET >
deny from all
< /Limit >
</FilesMatch>

Is there anything more that I could do to secure my WP with .htaccess? ANy other files to protect?

Thanks.
