Oh my god! I tried to do this exact same thing last night with absolutely no luck as well...
When you use the "Advanced Setup" it asks for an ftp server, a site name.. and it assumes the port.
Then it goes through its "Setup" and tells you your remote hosting ftp blogger account has been setup on your server for you.
Apparently the folks over at blogger think that minor things like usernames and passwords are unnecessary for ftp access.
I have no idea how to set it up either.
