Redirects and directory issues

Hi there.

I as so many before me are, am a complete novice at all of this. I registered a domain through wordpress.com, purchased hosting (Blue Host) and am trying to switch to wordpress.org. I exported, imported, set the original to private as the guide suggested, etc, but cannot seem to find my new website with ww.wp.xz.cn. When I set up the account through Blue Host/Mojo, it gave me a site URL similar to my WordPress Address which is not the domain as I intended it to be (and am not sure if that is the problem; attempts to redirect result in google throwing up an “oops” and everything still seems to run from wordpress.com. My ww.wp.xz.cn dashboard has me working from 69.19x.xxx.xx…. as if that is my site?). My website should be http://www.ajellyfishanilliterate. Please, please…assistance would be greatly appreciated.

Warm regards.
