Yes, the switch would need to support Cisco's FEC protocol if you  
want to use ng_fec with it.

Yep.  In many cases, a single 100Mbs link does just fine, but if you  
need more bandwidth, you can pick up a gigabit NIC nowadays for not  
much.  Picking up a GB-capable switch is more expensive, but perhaps  
your existing switch might have one or a couple of GB ports...
