I have two copies of the 18-55lens right now and will be returning one of them.  people mentioned make sure you get a good copy that iS sharp.  How do I test this?  I'm new to this and just want to make sure I keep the better copy.

I'd set up a tripod or some place to rest the camera and take photos with both lenses, making note of which one was which.  As someone else said, the difference is probably going to be that one of them is "softer" on one edge than the other.  Or maybe not.

shoot things with tall vertical lines, using the widest angle,

and look at the distortion that you will get.

But all 18-55 lenses will have noticeable distortion at 18mm, and it shouldn't differ between lenses.
