For instance, I meter something dark. The camera essentially ends up overexposing it since it is trying to make gray...so do I still add +1 to that reading?
No, you use your judgement to decide how much you need to correct for the dark tone and adjust from that, taking the fact that you like to shoot at +1 for a "typical" scene. So, if you have a black subject filling a large part of the frame, you would expect to have to use a setting about one and a half stops below typical to keep it black. In that case you would set it about half a stop under.
Similarly if shooting a snow scene, where you want to keep the snow white and the meter wants it grey, you would normally expose by maybe one and a half stops above typical, so allowing for your normal +1 that would mean setting two and a half stops above the meter reading.
I imagine my 5DIII is also around the same metering as others here, I am more often shooting at +ve EC (or equivalent in manual) but I don't simply set +1EC all the time. On a shoot it can vary between -2 and +3 depending on what I am shooting at the time, I suppose I am typically between 0 and +1 for the majority though. You just have to use the meter (and histogram) to guide you and your judgement to know when, and by how much, to modify the exposure. I shot an event a while ago when the whole event was shot at between -1 and -2 because they held it at lunchtime, in direct sunlight, with some participants wearing white outfits. One person I know left his camera at +1 "because it always needs to be +1 on Canons" and said I would get crap results. However, whilst I did have to bring up the exposures in post, my shots were fine and I had lots of detail in the whites. His, on the other hand, were positively glowing, they had huge white holes in the images with heads and hands sticking out of the blown out clothing.
So, yes, take the +1 into account, but also take into account what you are shooting and the lighting (+1 may still work with white clothing on a dull day) and if in doubt, take a test shot and see how the histogram looks. Remember if shooting raw that you are best with a "faithful" or "neutral" picture style as they give a more accurate histogram. Turning on the "blinkies" can also help as you can see where the image is blowing out - it may be somewhere that doesn't matter.
