Yes, you need bridging.

What you want is already done by me (same wifi card and same FBSD
version) :-).
I created my script with the help of the great sites:
http://www.unixcircle.com/features/802.11b_freebsd.php
http://stevenfettig.com/mythoughts/archives/000072.php
You can generate your not-so-easy-to-crack ESSID with:
# openssl rand 16 | hexdump -e '"%02x"'
And your four not-so-easy-to-crack wep keys with:
# openssl rand 13 | hexdump -e '"%02x"'
If you want to try the script for testing purposes first without
encryption, set "WLAN_WEP_ENABLED=0" in the script.
This is my working hostap start script:
