If any machine on your network ever goes outside (say a laptop), it can bring a virus in through the firewall. What you describe is consider "crustacean security": hard on the outside, soft and tasty on the inside. Plus there are lots of ways for systems to get infected through firewalls, via browsers, for example. Ideally, one thinks about security at every level: network firewall, system firewall, application access control, etc.
Jon, There are also plenty of free ssh/scp/sftp packages available for Windows. I use a command line version as part of the cygwin collection.
