I have a good idea, but need some help!

I want to make a cover art for a box set of all three films, with special edition covers of all three films and a special one for the box containing the three films, but there is one problem: I'm not sure how to make them. So can anyone help me???????

photoshop...
CS gives the exact measurements for a dvd cover page...if ur really serious i'll get u the dimensions, otherwise jus measure them urself...
i would suggest investing in VERY high quality paper and ink if ur printing them out urself, or get them printed professionally as well...
for the box...i have no clue how to make em.
