Hey Jim,

The addresses in your message are all link-local IPv6 addresses - 
http://en.wikipedia.org/wiki/Link-local_address#IPv6
Any interface with IPv6 enabled stack on any device on the network will have a 
link-local address (does not need to have a routable address assigned!)
Check the interfaces on your fw and other devices on LAN - the ending bits of 
the link-local address usually are specific to the MAC address of the device 
that's using the address, IE fe80::20c:29ff:feca:a0be belongs to a device with 
MAC ending with ca:a0:be

These are being caught/logged by the default deny rule, so you may want to just 
add another rule specifically not-logging blocks to/from fe80::/10

I don't believe you can completely disable IPv6 via webUI of pfSense - I know 
you can do this via /etc/rc.conf on FreeBSD, unsure for pfSense.
