As I have started playing with my D800 a little more, I have come across something I don't understand or can't quite grasp and am looking for some information.
I know the D800 does HDR capture (jpeg only, you pick the stops from base), bracketing you choose the number of shots all 1-stop apart and multiple exposures (I know this is taking two or more pictures and the camera "layers" them over each other, which sounds a lot like HDR).
That said, are my descriptions accurate? Is there a time when it would better to use over the other?
Seems to me that multi exposure would be the best of the three as you get in-camera processing of any number of exposures, but I could be thinking about this all wrong.

I believe you have misunderstood bracketing. It results in individual shots - not one layered (combined) shot. As well, they don't have to be 1 stop apart. See page 132 and following in the D800 manual. You can bracket exposure or flash value. You can bracket RAW and JPG images.
There is also a multiple exposure function in the D800 (see page 195 and following). That does create a single image but does not alter the exposure of the images. Rather, it calculates what the exposure should be then (if you choose auto gain) takes each shot at a fraction of that exposure. In other words, say you want 5 exposures - it will use 1/5 the exposure value for each image so that the resulting image is correctly exposed. You can make multiple exposures with RAW and JPG images.
In-camera HDR (page 176) only works with JPG and it combines two images that the camera exposes differently to increase the dynamic range of the resulting image.
Prevailing opinion is that if increased dynamic range is your goal, you're likely to get better results and more control by bracketing exposures then combining those images with HDR software rather than relying on the camera to do it for you. My experience with my D800E has been that the dynamic range is so good, I rarely even have a need to worry about HDR since I always shoot in RAW.
Using multiple exposure mode – I first shot the front of the car and then, after carful framing, I shot the word Cadillac. Like many of the in-camera processing this type of image layering is easier to do in Photoshop then it is in camera.
