Looks like the PCB layout software thought that legend should have been on the other side of the PCB for some reason. Very odd.
I haven't looked at programming Altera devices in detail but you've used a commonplace SPI memory this time. Hence the low cost. I don't know if Cyclone II can be programmed from standard SPI devices. I also note a JTAG port on the PCB. Cyclcone IV FPGAs can be programmed from JTAG but not sure if the SPI can be programmed via JTAG and the FPGA.
