Where to install Wordpress

[Jerrylee]

Hi'
Just one last quick question.
I want to install Wordpress as a stand alone blog with the domain name of cashblog-n.com.
In cPanel when I click on File Manager the box comes up giving me the options of all the domains I have there by themselves(cashblog-n.com) or with my main domain(cashblog-n.com.trygoogleadwords.com) added.
I would choose cashblog-n.com by itself correct?
Now I'm need to choose a directory to open, my choices being:
Home Directory
Web Root (public_html/www)
Public FTP Root (public_ftp)
Document Root for:
I know this is simplistic stuff, but I want to get it right the first time.
As always Thank You for your help
Jerry
