Firewall really necessary?

In my humble opinion...
It is always best to have a firewall between you and the outside world.  In some circumstances, two firewalls back to back is even better (make sure the two are from different manufacturers...)
The folks at work on tools which exploit open ports and even with so few ports available, your system could be used as a "zombie" tool by malicious people.
So, put a firewall in, or install some kind of syslog filter/analyser which will at least notify you of weird things going on...
