Chris, Not sure if this is helpful but it appears the next step that is failing is the actual connection to tomcat from apache (unless you've left this part of your mod_jk.log out of your post).
Here's the mod_jk.log output of a test I did on my local machine. The first worker 'testworker' connects successfully; while the second 'newworker' fails at about the same point you appear to be failing. In the below case, 'newworker' fails because it can't resolve the tomcat address after it sets the contact for 'newworker'. Don't know if this helps or not...
