Alright, I just got a copy of Aperture and I was just wondering if there was any need or use to keep iPhoto or can I just do everything in Aperture now as far as viewing and editing photos and delete iPhoto? 
I'm not sure seeing as I don't use Aperture (I use Lightroom), but not having the ability to easily export slideshows from iPhoto is a real pain.Can Aperture create slideshows with Ken Burns effect and export them for iMovie or iDVD?

I doubt that will work. Aperture does not create new versions of the pics after edits, so you'll only have access to the originals. You'd have to rotate or whatever other modifications you did once again in iPhoto.But you can tell iPhoto not to copy files on import and then open the Aperture Library in iPhoto. You can then use iPhoto to do all these things will the rendered previews from Aperture.
