How would I go about completing this PC (I'm a PC building newbie)?

I'm going to add a 1.5 terabyte hard drive and DVD burner, but what else is needed? Do I need a video card and sound card? or does this combo have one? What are the remaining components I need to buy?

Would I also be able to upgrade this to say, a core i5 processor down the line?

Thanks for any help =] I can't wait to get started.
I don't play any PC games (except those really casual ones like Family Feud); I do edit HD videos though, so I would I need a graphics card for that?
Yeah; I have Windows 7 that I'd install.

You need an operating system and a video card but other than that you're good. You will be able to upgrade to an i5 or i7 down the line as long as its socket 1156.
