Fix up hacked Joomla site

I have a clients site that was hacked by hmei7 I have removed all of the offending files I can find however cannot get to home page (msg Fatal error: Class 'JCache' not found in /home/unc16889/public_html/libraries/joomla/[login to view URL] on line 208) and cannot get into admin (1st msg Fatal error: Class 'GalleryCoreApi' not found in /home/unc16889/public_html/administrator/components/com_jfusion/plugins/gallery2/[login to view URL] on line 46) then eventually I do get in but then get different errors. I would like the site fixed and secured. It is a small straight forward site for a charity organisation. Thanks
