Hi there!
You can set up natd+IPFW or use pf only. I think bridging is not necessary in 
your case.
Proper filter rules will give your freebsd system good protection.

Some information could be found in the Firewalls chapter of the Handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html

Great explanation of pf functionality here:
http://www.openbsd.org/faq/pf/

I find pf approach much easier to set up and maintain.

Google search will give you more ;)

Good luck!
