Hi jimzoy - and welcome!
Perhaps a good place to start is Site Helper:
http://www.site-helper.com/
Do UGS have a knowledgebase or support portal? Perhaps send them an email.
Without knowing excactly what you need help with, I'm guessing since you said you've already got a website - you will need to upload your website to your FTP account.
To do this, you need an FTP client (like FileZilla - you can get FileZilla from http://www.filezilla-project.org).
Site Help "how to upload" page: http://www.site-helper.com/uploading.html
Interesting that your hosting provider doesn't offer Domain Registration.
