I learned to manipulate div overlays by downloading a free template then changing things to see what was effected. I found it easier to grab a freebie then change it up as I went.
I will add that I no longer do this because MySpace changes their code so much it was a full time job fixing broken code every other month.
But, when I did I found the following blog to be very helpful.
