No. ebtables come after the bridge is set up. Consider ebtables a form
of access control. It's not mandatory to use them by any means.

Of course you're not the first. So...

First, I suggest you to change your WPA authentication right away, as
you've just shared your WPA key with all the world.

Second,

This part is wrong. You want to bridge some interfaces to wlan0 via
br0, yet you don't include wlan0 into the bridge.
The correct way of doing this should be:

bridge_ports eth0 wlan0

Assuming, of course, that you'll never want to have different IPs on
eth0 and wlan0.

something strange goes here. You've told interfaces(5) not to add wlan0
to br0, yet there's someone who tries to do it. Is it the manual
invocation of "brctl addif"?

"can't add wlan0 to bridge br0: Operation not supported" should be
easily defeated with good old:

iw dev wlan0 set 4addr on

I.e. edit your /etc/network/interfaces like this:

auto wlan0
iface wlan0 inet manual
      wpa_ssid  XXX
      wpa-psk   YYY
      pre-up /sbin/iw dev wlan0 set 4addr on
