You need to set the correct fuses for your board, in order to get it to run at 8Mhz, use the following site to calculate the correct settings:
(I've set the fuse bits that I see as the optimal settings)
Next you need to program your bootloader into the device, find a copy of optiboot, and compile it for atmega328_pro8 profile which should provide a hex file that you can program to your device, using an available ISP programmer, with avrdude (or whatever tool you like to use).
