Joomla site hacked fix

Our website that is Joomla based was hacked and started creating redirects to another website ([login to view URL]). I deleted the files that were causing the redirect and re uploaded another clean version of Joomla keeping the old [login to view URL] and the old configuration and not uploading the installation. I also re uploaded all images, and other files that were needed for my website. The redirects are gone, but the site is not loading as it did before. There are errors, and when I try to get to the homepage all I see is a login screen and link to the website. I need someone to look over my site and identify the problem and help me get my site functioning online. I need to make sure my database is still in tack (I have a copy if there is a need to reinstall on mysql). I have all the template files, components etc but missing some library files for Phoca gallery etc (may need to reinstall phocagallery).
