Thanks, I'm probably going to go this route. Crossing my fingers for the best!...
Cheers,

Just my two cents.
Well, basically by top case, I mean that the keyboard and trackpad are completely unresponsive. Backlight works, but not the keys or trackpad at all. I was getting slight artifacts before the keyboard died, but I was still in school, so I continued to use it with an external mouse and keyboard since I couldn't be without my laptop during finals.
As far as the screen went, they said something about seeing pressure points. On my Genius Bar work authorization form though, they listed the keyboard/trackpad and observed graphics artifacting on the sheet, but nothing about the screen, and nothing but "normal wear and tear" under cosmetic condition. I never got a chance to test if there were artifacts when using an external monitor yet, so if I'm able to, I'll definitely try to get that happening and make record of it.
When I go pick up my laptop again from the Apple Store, I'll be sure to bring up these points with them. Considering the GPU test wouldn't even run, and the list of problems states "Observed graphics artifacting," I hope they don't give me too much trouble. If not, I'll try to ask for a replacement if all goes well, though I assume I'd have to speak to a manager.
Thank you for the advice!
