hacking threats

[mystic10]

i read all the stuff you guys had to say about security...now i have question:

http://www.javascriptkit.com/howto/htaccess3.shtml[/url] but still confused where to start
k so i am trying to do this is this right
i dont have shell:

AuthName "Restricted Area"
AuthType Basic
AuthUserFile /home/yah00-city/admincp/index.php/.htpasswd
...since its not shell is this ok or do i need to put it like this:
/home/yah00-city/public_html/admincp/index.php/.htpasswd
AuthGroupFile /dev/null
require valid-user

and do i name my notepad as..admincp.htaccess

and than make another notepad and save that with admincp.htpasswd

or this is not right
----------------------------
also someone suggested this with ip how do i go about writing that...
unique IP address you can edit the .htaccess file in your admincp directory with.

order allow,deny allow from <your IP>
allow from <admin2's IP>
deny from all

thanks for u help in advance
