There's a good chance that the version of Aperture you downloaded isn't legit. Same thing for the Digicam clone .dmg you downloaded. These could be filled with programs that could damage your HD and files.
Fist things first - since you're running Snow Leopard, the App Store version of Aperture won't work as it will only work on either Lion or Mountain Lion. You'll need to decide if you want to upgrade to ML first. You're alternative is to BUY the retail version of Aperture from someplace like Amazon.
My gut level feeling is that the software you downloaded may have damaged your OS. My personal recommendation would be to do a clean install of Snow Leopard (after you manually copy all of your data to an external drive that doesn't have any of the crap you downloaded on it).
If you need a good data rescue program, Data Rescue 3 is probably the best. Yes, it's expensive, but it's saved my butt multiple times (even recovering data from a WinDoze drive).
One more thing...quit downloading stuff from torrent sites! Buy it legit!

To protect yourself from emergencies like this, you need a good backup strategiy. i.e. before installing new software or upgrading software, backup your system. And to be able to restore the previous state quickly, create a bootable clone.
Cleaner apps, like MacKeeper, are no protection against unintentional system damage. They will cause more harm than the will help.
