Both the server address, username and password should have been given to you by GoDaddy. If 'usdeafsoccer.com' doesn't work, try 'www.usdeafsoccer.com'.
And if 'public_html' doesn't work, try blank, 'www' or 'www_docs'.
It will never be index_html. Index.html is the name of the first page you have created in VSD.
If you still are not able to connect, try an independent FTP client like i.e. Filezilla (free, google for it) and check if you are able to connect using that. If you are, then check what settings you used and use the same in VSD. If you are not able to connect, you'll have to contact GoDaddy and ask for a more detailed instruction.
As to who is working/helping during weekends, those who have stepped in here are not CC staff. We are just voluntary helpers.

Edit: Sorry I used 'deafsoccer', not 'usdeafsoccer' in my sample pic.
