You need to contact your web host and ask them how to go about uploading files via FTP. What you first posted were links from within CPanel, the second was with phpMyAdmin (a MySQL management tool).
If you are on a CPanel based server, your FTP login information should be the same as your CPanel login information. So what you login to CPanel with, you should be able to login to FTP with.
The hostname should be your domain name, your username would be the CPanel username and the password your CPanel password.
