Firewall type can only be one value.  You have both /etc/ipfw.conf & 
workstation.  If you use /etc/ipfw.conf, then the rest of the options 
other than firewall_enable are not needed as you will configure your own 
rules directly in the ipfw.conf file.

However if you use type workstation instead, then to enable the 
myservices, then you also need is firewall_allowservices which tells it 
what IP network(s) are allowed to access the myservices.  You can have 
more than one IP network listed, but you separate each with a space and 
not a comma.  Likewise, the myservices are separated by spaces, not 

firewall_myservices="NFS SSH NTP"

I don't use the logging to much myself so I may be missing something but 
I believe the places to look would be /var/log/security and or execute 
"ipfw show" depending on what info you're looking for.
