Getting Started Using BlueHost and WordPress

I joined elegantthemes.com today and downloaded the theme (Deep Focus) to use for my photography website. I tried many different ways to upload it to wordpress.org (while first realizing that you can’t do that through wordpress.com) and finally looked at the FAQ, forums and videos on YouTube which suggested that I use an FTP server. I chose the “one click option” for my server and got an account with BlueHost.com (which they recommended) and am still having problems linking my website to wordpress.org.

I think what happened is that last month, I purchased my domain name: http://www.laurentinaphotography.com from godaddy.com and linked it to my carbonmade.com site. Now, when I try to login to the wordpress site so that I can upload the theme and work on the site, this is what pops up – http://www.laurentinaphotography.com/wp-admin. How do I undo this?

I also somehow signed up for a wordpress.org forum account, but still can’t log into the site and use the dashboard. What’s going on?

ANY HELP about this topic is greatly appreciated. I am a total beginner at web design and know that it is probably not as confusing to some as it is to me. All I want to do at this point is to get my theme uploaded onto the wordpress.org site so that I can start to create it and eventually use the domain name “www.laurentinaphotography.com” for the wordpress site, instead of the carbonmade one.

THANKS IN ADVANCE FOR ALL YOUR HELP!
