are there any ready to use FTDI modules available on Digikey or Sparkfun? If so could you kindly post the link?

I purchased these two modules:

Are there any additional hardware that needs to be soldered on to a PCB to make the DE0 Nano <-> FTDI chip interface work

No extra hardware needed. I plugged the UM245R module into the BEMICRO-PROTO board and tested the asynchronous FIFO interface. I haven't tested the FT2232H and its synchronous FIFO interface.

What protocol is suggested to be used to facilitate communication between the DE0Nano and FTDI chip, (for e.g. SPI or I2C or UART) to get a speed close to High speed?

The UM245R FIFO mode uses an 8-bit data plus 4 control signals interface.
I haven't looked at the requirements for the FT2232H synchronous FIFO interface.
