I figured out what is going on with your second issue.
All of the ticket subjects that have lost their link are really long and have been truncated using jQuery.
Unfortunately, for whatever reason, the jQuery is behaving differently within your installation and is stripping away the anchor tags.
It is a really easy fix.
Open /include/staff/templates/queue-tickets.tmpl.php and change line 355 from
jQuery(".truncate").each(function(i, value) {
to
jQuery(".truncate a").each(function(i, value) {
