You can plug in a hub / switch with no issues. It's not like a router (which acts like a computer in its own right) but rather just a box which funnels data from multiple sources into a single route (like a 4-way electric socket).
a four-port hub would probably do you.... Unplug the cable from the router to the PC and plug that into the hub. Get two more cables and connect your PC and Mac to the hub. As if by magic should all just work :-)
There are some firewire networking implementations, but it'll be *much* easier to get a cheap hub and a couple of short cat-5 cables. Really.
I have a 4-port router, into which is plugged a wireless router and an 8-port switch (hub). Two laptops (one of Mac) and a PC connect via wireless. Three other PCs and a Mac connect through the switch to the router. It all just works :-)
