Setting up a single SATA drive in a computer?

I bought a new mother-board some months back, it is a Gigabyte GA-73PVM-S2H, with a Dual Core Intel CPU.

Now this MB, has support for 1 IDE HDD, which I have the MBR installed on.
All of the other on-board storage sockets are for SATA drives.
I have a DVD burner/drive and a new Western Digital 500GB HDD I would like to install.

No matter how many times I have read the manual (a PDF these days), it is written in such a way that I'll be blowed if I can understand what on earth they are on about.

From what I can work out, I don't have to create a RAID array, for the one HDD, but is the DVD unit included in what could be called an array?

I've been putting off installing this gear for about 6 weeks, as you only get one chance to do this properly, without affecting the current IDE HDD.

Can someone please HELP!!!!

I've never had to work with SATA before, I wish I didn't have to now either.

BTW, there was a mention of having to make a floppy disk, with some data on it, my computer does not have one of these sorts of drives, neither do most newer computer these days, how do you get around this?
