Thanks 2 the both of you for the responses. Without a grille to obscure my view, I ended up figuring out WHICH cable was the correct one (lightly tugging @ all of them lightly)...Then I had to buy batteries for a flashlight that hadn't been used it ions, but it helped me find where I had to perform "screwdriver methon". It popped open just like that! The metal on the latch under the hood is really oxidized, so I'm sure that made it more difficult.
I do notice Richard, that the cable is in fact really loose and cannot be pulled tight enough to pop it open from the release latch under the dash. I know the cable itself isn't snapped because I can see the slack portioin in the front tighten up when I pull on the under-dash release latch. Or so I'd like to assume?? So, as suggested, I will look to disassemble it and tighten the cable. I'll check the rubber on the fire wall as well. Question though: Where exactly do I need to lubricate? The release latch under the dash and/or the metal latch mounted under the hood?
Sorry for all the novice"ness"; I still can't find anyone with a manual!
