Building my first pc?

Hi, I'm going to take the plunge soon and build my first PC. I'm going to have all new parts, a gigabyte motherboard and seagate hardrive. What order should i put the parts into the box and what should i look out for that can catch first time builders out. also i hear something about jumpers set up on the motherboard if anyone could explain that too me. Aswell could anyone explain what i should do once i turn the box on for the first time and when to install windows xp. thanks, here is the motherboard. Any help would be appreciated, John.
