i can't connect to my site with FTP with any combination of settings I can find

my web address is http://quotes.zxq.net/

I need:

- host name: 74.86.20.181:21 ( host name right? use a port number? like this?)
- address: quotes.zxq.net (port.number.here:21)?
- user: (quotations1000@zxq.net) or (quotes@zxq.net)
- password: (account pw) or (control panel pw)
- Passive mode
- protocol: (FTP or sFTP)
- file name encoding: ISO 8859-1
- proxy type (this is a firewall thing?)

- anything I'm missing??

are these right?

thanx, Nate
