With small SLR bodies like this, when is it appropriate to remove the lens and store the body with the body cap on it? Does the cap offer dust and dirt more access to the mirror box than a lens does? Does it affect the lens to be on the camera while stored for long periods of time? What are your arguments for your method?
Probably an insignificant question, but I want to know what you guys think, and I want my gear to be healthy.

The only time you need to remove the lens for storage is when you are storing the camera someplace that the lense will not fit. If you have a place where only the body fits, then the lens must come off. The body cap affords the same dust protection as the lens. However, everytime you remove the lens you allow the chance for dust to enter the camera. When the lens is off ALWAYS store it with both the front and rear caps in place to keep the elements dust free.

I usually leave my 18-200 on the D40 body. I only change lenses if I have to, and then, if you are going to change lenses, always do it indoors, in an environment away from dust. These cameras are very sensitive to airborne particles-the sensor/low pass filter area has a charge around it, and brings things in like a magnet. Leave the lens on your body, unless you want to swap lenses out. When doing so, make sure the bayonet body opening is facing down. I try not to make frequent lens swaps. But, I always store my camera in the bag, with a lens on. And a cap on the lens, of course!

It's not at all an insignificant question...!
The joint between lens and camera will generally be tighter than that between body cap and camera. So from that point of view, you're less likely to have dust entering the camera if you store it with a lens fitted. There is really no problem with doing this, unless (as mentioned above) the lens/camera will not fit where you want to put it.
I do think, though, that those who advocate changing lenses as little as possible, and only in clean conditions, are taking things a bit too far. SLR camera are designed to have interchangeable lenses - that is their whole reason for existence. As long as you use reasonable care, there is no problem at all in changing lenses while you are on location

i don't store the camera without the lens. the last one used stays there until there is need for another. some suggest storing it with the lens pointed down. it seems a good idea to me. the dust inside is more likely to fall on other parts than on the sensor.

Why would you want to store it for a long period of time? Mine never goes un-used for more than a day or two. I don't worry too much about dust in the sensor and I change lenses when needed, whether inside or out. Once a week I clean the sensor with my Giottos air blower or if I notice anything in an image.
I learned the hard way many years ago that the only way to get once in a lifetime photos is to have your camera with you. I was driving into Anacortes, WA on a business trip and there was the most beautiful image of the moon rising over Mt. Baker and both reflected in the dead calm water of Puget Sound. I had left my camera at home in Denver because it was just a short trip. I was there several times after that on business but never saw the same image again.

I'm with those who never remove lenses from camera bodies unless necessary to change them. I store all my DSLR bodies with lenses on, in a large drawer resting on their bottom plates.
When changing lenses, I always do so with the camera turned off. I place the next lens to be mounted on a flat surface and loosen the rear lens cap. I then remove the current lens and place it on the surface beside the next lens, while keeping the camera body face down to avoid dust settling in it. I use a rubber blower on the rear of the current lens when I remove it. I then blow out the rear lens cap and the rear element of the next lens, and place the cap on the removed lens and the next lens in the camera. I then tighten the rear lens cap on the removed lens and store it in its case.
Yes, this method is a bit cumbersome and not all situations leave time for it, but I rarely get dust bunnies in my camera sensors.
