Moved my site, now I can't login to my admin?

I have a wordpress site that I just created and I have external hosting and domain thru website palace. I just moved my site from the http://www.domain.com/wp to my personal http://www.domain.com, but now that I did that my site is missing some of the images, widgets, pages and theme that I had previously. Along with that I can no longer access my wp/admin to make changes. What do I do to repair this?? HELP!
