Sounds like two unrelated issues.
The slowdown is probably a failing HDD. The line through the display could be a display failure, but it would have to run through the entire screen, and affect everything equally. It also likely wouldn't show up on a screenshot, unless you took a picture of the screen with a camera or something.
This afternoon, I ran the Apple Hardware Test that came with the restore disk and it passed. I also booted off the Snow Leopard disk and ran Disk Utility, checking the hard drive. It passed that.
My wife had a MacBook Pro with a similar problem, though the horizontal lines she was getting were thin black. The one on mine is wife and slightly wider. It extends through the browser (usually the top most app) and across the desktop. Turns out my wife had the logic board replaced and that fixed the issue, which is why I was worrying about that option.
