Buddy,
Most of the time, the juicedrops are fine the way they come from the factory. They come in a few different formats, including layered PSD, RGB tif and CMYK tif. You can import the flattened images straight into corel. You can then use them however you want, either powerclip them into something or use them for a wrap or whatever. You should be able to open them in the photoshop you have in case you want to manipulate at all, but you shouldn't really have to. Have fun!
