I'm not terribly organized. I tend to keep things in felt bags and set them on shelves, or on chairs, or on the dresser, or in other out-of-the-way locations. Once in a while I'll pick up a bundle, open it up, and discover a camera I haven't seen for most of the year, together with a lens I'd wondered about a couple of months ago, with a roll of film half shot... It tends to be the next one I shoot with.
Special precautions? No, not really. It's tempting to keep things in zip-loc bags because they're so convenient, but I don't because of the potential moisture damage that can accrue. I use AA Lithiums in most of my cameras; they're expensive, but long-lived and light weight. So when I tuck a camera away for an extended period I remove the batteries, primarily to use them in something else. I use body caps on everything.
