When you changed permalinks, did you CHMOD .htaccess to 777 beforehand or implement the recommended settings the Permalinks page specified into .htaccess?
I imagine that the Facebook/Twitter settings will not restore, however, I could be incorrect. Please make sure that the permalink changes were set into your .htaccess settings. If not, go into your installation via FTP and CHMOD the .htaccess file to 777. Return to Dashboard > Settings > Permalinks and simply re-save without changing. See if that helps.
