Nothing in your arp list appears to indicate that you had involvement from
any device other than the two you own. Of course and arp list is far from a
complete record of activity.

239.255.255.253 = uPnP (disable on router if not needed)
224.0.0.x = Multicast IP addresses (router autodiscovery, etc)
1:0:5e:x:x:x = Multicast MAC addresses (separate from hardware MAC
addresses)
169.254.x.x = Automatic private addressing (no DHCP server available for
devices configured as DHCP clients)
169.254.255.255 = Broadcast address for automatic private addressing space

Airport Express Firmware 6.1 automatically checks for other WDS nodes - new
autodiscovery feature, introduced 2004-11-15 per Apple's site. This sounds
relevant to your issues. Did they occur after a firmware update?
