Erin, you posted a similar question here and were answered with links to other threads that would help.
I would also recommend reading some books on getting a web site up and running. The "Dummies..." books are very good and I used them when I got started. We all have to start somewhere.
You can also find more infomation on the FTP help page including a link to a movie tutorial.
Hope that helps.
