1...Firewall

Everything I have read tends to point to "roll your own" firewall as 
a better alternative.  In other words, learn to use it.  
I know it's difficult, but it will be worth it.  The 
"go'n buy & setup" sound like M$-plug-and-play.  It would create a 
generic firewall.  It may or may-not full protect your system.  I would 
recommend reading 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html
as well as reading the freebsd questions mail archives.

2...The following quote:
"which will shutdown until all system-files are moved into RAM"
maybe you ment to say move out of ram before shutdown.
If you have a "UPS", then good, otherwise consider getting one.  You 
could end up with a corrupt file system.

3...Do you have a cd-rom drive?  You could run Freesbie:
