Son messed with firewall settings - now I don't know if I reset them correctly

My firewall settings were changed by my son.  I reset to default but then almost all of my connections were blocked (my mail would not download, my printer would not connect, etc.)  So, I tried to configure it but I am not sure that I did it right.  I only use my lap top at  home and my only other network computer is my desktop Mac.  Both my Macs run version 10.6 if that matters.

 

 

 

So, can anyone tell me if I did this right or is now my computer totally accessible to anyone? 

 

Thanks for your help.
