You don't necessarily need more physical interfaces. You can use any switch with vlans and use 802.1q subinterfaces.

Agree with Paolo, that you might want to consider using subinterfaces on one or both your existing FastEthernet interfaces. However, for "routed" Ethernet options, see: http://www.cisco.com/en/US/products/ps5854/products_relevant_interfaces_and_modules.html#ethernetrouted. Also, you can route using Ethernet switch modules via VLANs, so you might also want to examine: http://www.cisco.com/en/US/products/ps5854/products_relevant_interfaces_and_modules.html#esm
