Simple Question, Do i need anything else to run a cap other then the battery, 2 power cords, the cap and the amp? I read somewhere that you need Buss bars or somethign like that. Im only running 1Farad Cap before my 800RMS Amp.

You will need to charge the capacitor first. If not, when you try and connect it to the battery, you'll get a big spark.
Use a 12v light bulb to charge it safely.
If the amp is truely 800w rms, then 1F will not be enough. You'll need 1.5F or 2F.

are you sure about the 1.5-2F? Specs state that 1F is good up to 1000RMS

Mount them as close to the amplifier as possible, and choose at least .5 farad (500,000 microfarads) per 500 watts RMS of power output.

I do believe (if i'm not mistaken) to use like a 1k resistor to charge your cap slowly to the desired 12/14vlts.
