OK, if you have eps, (I'm assuming vector), as an Illustrator file already, what are you doing trying to put them in PhotoShop? You have what you need and if you rasterize them in PS you will no longer have a cut pattern.
If your just using the "template" in PS to work on the design, just leave in on a separate layer, do you raster work, delete the template layer and than PLACE your PS image back into the template in Illustrator.
By the way, just "converting" a psd image to an eps does not mean you will have a usable vector outline to cut from.
