I would first try and figure out why Wireless clients could access
machines behind the firewall from outside.  If thats correct the
firewall isn't stopping anything and you have bigger problems than
figureing out where to put an AP.

Bad idea...WEP is too easy to hack through.  Even with a MAC ACL you
are still to exposed to risk.  APs should always be in a secure DMZ w/
VPN.

Is it a router or a firewall...a firewall shouldn't allow any unchecked
traffic from the internet to the inside.

If the Access Point is intended for general, on the street passer-bys
then your idea is perfectly find, though a disclaimer would probably be
a good thing releasing them from any liability a cracker targeting
other people could generate.

If the Access point is intended to be primarily for company use, it
should be in a DMZ (that restricts outboud traffic) and uses VPN to
access the internal network.
