I've seen the schematic, but it's not totally clear: For my project, I need both a serial port (to drive a MaxStream XBee) and a SPI port (to drive an SPI peripheral). Does the Arduino USB board provide both interfaces?

need serial port and SPI port

Yes, although the SPI port isn't currently "exposed" through a nice interface, but if you do some searching on Google, you should find code for it.
