What OS are you using? Aperture won't do you any good unless you're on a Mac.
As to having Aperture and Lightroom in a "bundle", well, it really won't work well trying to use them together. If you have a Mac, well, you could install both and then pick which your prefer, but that's the only decent reason for installing both.
Whichever you choose, though, you will want to get a "pixel editor", it could be Photoshop or Photoshop Elements, or any of the numerous apps that allow you to manipulate images in ways that neither Lightroom or Aperture do. The academic discount for Photoshop is certainly nice, and if you have the funds, getting it plus Lightroom or Aperture will set you up with the best, but if funds are a consideration, you could look at Elements, which has a lot of Photoshop photo tools, but not as much as the Spendy version!
