Transfer site to another domain error

Hi! I designed a site on wordpress under the domain of http://www.hurrikanedesigns.com/cam. My client finally purchased their domain using the same hosting company. I followed the procedures on transferring over the files to the new domain but on the site all the image links are broken as well as all the plugins have errors and did not install. Do I have to just manually install everything again?? or is their an easier way?? Need Help Please!!!! Thank You in advance.
