I have been running my network exactly like yours since the fall of 2001. I even removed ZAlarm.  My understanding is that all that is seen from the internet is the router, and most have built in firewalls.  From the beginning I have used file sharing with TCP/IP, and have had no problems. A real intent hacker could probably break in, but I don't have anything on my home computers that anyone would want.  I remove the stuff I want to keep every day to zip disks, and IBM microdrive, and eventually CD's. Hackers usually want some return on the investment of time it takes to hack in, so I'd think they would want sensitive corporate, government, or financial institution victims.  I do watch mostly for virii in my e-mail and in my downloads.
