I was wondering what is so special about the Optima Batteries? Are they really even necessary for third gen F-Body's? I can get one with 980 CA and 800 CCA. Is that too much Juice for my car? Is there such thing as OVERCHARGING??

Optima batteries are dry cell batterys so they dont have any liquid acid inside. That means you can mount them in any position you want and there is also less danger of acid spill in an accident. You by no means need one in a thirdgen.
Both of those batterys provider more than enuf amperage to power the starter. Even half of those cca's should be enuf to turn over the starter.
There is such a thing as overcharging but it isnt caused by to big of a battery. Its caused by the alternator putting out more voltage than it is supposed to. So as long as your alternator is functioning properly you have no need to worry about overcharging.

They also use spiral cells, which greatly increase the plate surface area. That's what gives them the insane CCA's for the size they are

Just as an added note, I remember reading a thread a while back about the red top ones. If it was completely drained, it then has a hard time holding its charge afterwards when recharged. Correct me if I'm wrong guys. I'm still gonna get the yellow top one though

That's true with most any normal batteries. Only deep cycle batteries will completely recover from a complete drain usually.

So if you want a battery you can drain down all the way, and have it not retain a memory, it's a yellow top you want. Just keep in mind that the deep cycle batteries last their longest when you can completely drain them down, and then fully recharge them.
