I haven't gone to a router - yet, so haven't looked much into the details, but the conventional advice is that you should have a firewall at the router. Some(?) routers come with built-in hardware firewall features, and most have software to do some protecting.

The PC Mag issue that's up as the current issue (see noon-15 above for link) was focused on networking, and should have some discussion of what security you should have, although they're pretty hot on the wireless stuff at the moment.
