For arguments all I use is Node:NID Provide Default Argument > Node ID from URL
DUDE!!!! Holy crap I can't believe I didn't see that option!! I imported your view and it looks great! I am modifying it now and also working on my other views I got going for Quicktabs. I am getting really excited over this finally!! woooohooooooooooo!
EDIT: Ahhh I C. This option was not available under "Hide view / Page not found (404)", but instead under "Provide default argument".
