The I/Os are TTL level so no converter needed.
There's already prototyping space on the Olimex PCB linked above.
There are American distributors for Olimex.
Propeller's use serial over USB for debugging and bootloading.
Emulated serial over USB is by far the most compatible mode of operation.
I've used it in Windows, Mac OSX, Linux, BSD, Android just to name a few.
Avoiding the HID layer you can program in a wider range of languages and avoid some interesting issues.
I've even got shell scripts that can take input from serial ports that are really USB connected.
