Du'oh!
I changed it and this is what I see so far. I'm running a Nessus scan on one side of the bridge and the target system is at the other side of the bridge.

I should see some sort of log file in /var/iptablequeue/post_queue or /var/iptablequeue/pre_queue now? Should I try sending packets through the bridge to generate something?
uh--no. those rules might not even load. "--log-prefix" specifies a string to prefix the log entries in your syslog files. my rules were literal:
/usr/local/sbin/iptables -A FORWARD -j LOG --log-prefix "PRE QUEUE: "
...
/usr/local/sbin/iptables -A FORWARD -j LOG --log-prefix "POST QUEUE: "
so the entries in /var/log/messages will have the strings "PRE QUEUE: " and "POST QUEUE: " in them for identification purposes.
