Why? I suppose if your internal HDD has 3GB of space left, yes, but I'm working with the assumption that you bought your laptop in the last 5 years and haven't filled it with 80 movies and 50 albums.

Lens: I've got the Nikon 200-400 and sort of wrote off getting a TC because of thom hogan's (www.bythom.com) comments about using it with that lens and, separately, using it on safari. however, it couldn't hurt too much to get and plan on not using unless i figure out it's necessary. but then if i'm using a 70-200 and 200-400 i'll have that large 80 gap at 200-280
I'm not seeing an 80 gap. I'm not sure how much you'll get out of the 70-200 since I believe safaris will keep their sweet distance from the subjects. Still, good to have. That said, if there is an 80 gap, I wouldn't worry too much about it, you don't need every single focal length to take good pictures, and by the time you switch lenses, your subject might have moved farther/closer anyway.

Priority: I think I'm too new to go full manual
This is exactly why you have to practice at manual. You're not going to figure out how to balance all this by having the camera do the tricky part for you (setting the exposure through the non-prioritized options). At least try to go full manual for 50% of your shots, and do your auto thing on the other 50%. At least then you're guaranteed to have 50% of your shots properly exposed.

Histogram: way to fix this aside from moving the camera is through the EV adjustment, also changing shutter speed/aperture?
I'm not sure about your camera, but on some the EV adjustments can cause some serious clipping. Personally, I would only consider aperture/shutter speed/ISO. If you want good DOF, prioritize aperture; good action shots, shutter speed. It varies by camera, but try to keep ISO 800 and lower; higher can start to produce some nasty noise.

ISO: so if I'm shoot in shutter mode I'd set the shutter speed to what I need, say 250, then keep adjusting ISO until there's enough light? what about EV here?
This is one of those, I'm a bit rusty things (and used to film), but EV is a priority mode only on your camera, yes? You're basically just telling the camera that its default exposure for a given shot isn't right, and are telling it to adjust itself. Depending on your priority mode, it will change one/both of the other two values to do so. This is for when you're not happy with the default output in a non-full-manual mode.
On other cameras, this EV stuff could mean in-camera gain control, which really shouldn't be used since it's better done in post. Someone else feel free to wade in, as this gets into the technical side of things regarding different cameras and firmware.
As to the rest of this comment: this is why full manual is best imo. If you have a mode where you can determine two of the big 3 exposure aspects (shutter/ISO), and then you still want to change your exposure, and if your camera uses EV to affect the untouched settings, setting EV is just a roundabout way of setting the aperture. Personally, I wouldn't ever let a camera set my aperture, nor my shutter speed. The first has a huge effect on the shot's DOF/sharpness, and the second can be vital if in motion or shooting such a subject. Assuming your lenses aren't high quality, you'll probably want to stop down heavily at such tele ranges to maintain sharpness. Since it's Africa during the day, you can probably do f/16 and then pick maybe 400/400 for shutter/ISO. Your lens might be a bit dark, though, so probably not 400/400. f/16 might be excessively restrictive, though, so I wouldn't use that as a 100% rule on such a shoot, especially because tele shots and shallower DOF can produce some great shots, which f/16 is going to really hurt/prevent. This also brings us to ND filters. Get a couple of varying strength to free your aperture up in high lux environments. This will be an extra $40-100. Make sure, as with all extra glass, that they're multi-coated and from a good manufacturer (B+W are the ones recommended for a lower price point to me a lot, but I'm not expert on all the different brands).

Post: will definitely get a book or do some major tutorial reading soon. It's pretty much mandatory to process everything right?
It's not mandatory since a lot of new cameras come with pretty solid built-in shooting modes, but it's usually highly recommended. I mean, your gorilla pic was in definite need of post work. Some of your shots will need it more than others. If you're shooting for post, remember to shoot flat. This will produce a fairly unattractive picture out of the camera, but the point is to give you as much info to work with during post as possible (and you can always keep the raw file and rework it later once you've got your post skills up; you can't ever/usually go back and retake the pic, though). Flat means a neutral shooting style (neutral/faithful are usual terms), lowest contrast, lowest sharpening, lowest saturation settings in the menu. Due to compression, some cameras aren't best to shoot flat like that, but this is something you'll need to find out about your particular one.
If you shoot 50% auto and 50% full manual, you'll have 50% pics that are "pretty good" out of the camera and 50% that range from "tossers" to "needs a lot of work but is v promising". This approach also gives you good baselines to work with when you're doing post: the auto version is the camera's best, try to beat it. As your skills improve, you will be able to.
Basically, you're going to be on safari, and will probably have a TON of time to practice with all your settings and the pics they produce to figure these controls out. You really can't ask for a much better way to learn photography.
