Another New PCB for Arduino Serial Single Sided

Hi,
I am a total noob.
I want to make one of this board cause I cant get any Arduino here in my place but I can getAtmega168.

Question:
Do I need to upload the bootloader to the Atmega168?
If so how could I do that with this board cause looking at the software side the bootloader only can be upload using parallel port.

Thanks and regards.
