I've noticed that my screenshots are not crystal clear. It's frustrating because I am using them for design. I've exported them to JPG, best quality and PNG. Neither has resulted in very good screenshots. I'm using command+shift+4.

Not sure what you see. Screen shots are as clear as your screen. You should leave them as .png files. Converting them to .jpgs will lose some quality. And of course, enlarging them will as well.
I always use the Screenshots app (located in Applications-->Utilities). You might try going that way.
Can you post a "blurry" screenshot here so we can see how blurry it is?
