I'm not much farther along the experience curve than you are, but here are a few things I've learned that they don't seem to tell you in the "standard sources":
(a) Everything dehydrates well, as long as it contains almost no fat or oil, and anything solid (meat, veg) is cut into small bits: shreds or small thin pieces (think 1/2" length of popsicle stick) for meat, tiny dice for veg. Smaller pieces rehydrate faster, but I like the pieces of food to be big enough to taste separately

(b) For meat-in-sauce type dishes, I find it easiest to cook the dish the way you normally do, let it cool, then pick out the meat chunks and slice them into dehy-size. Dry the meat and sauce separately, then recombine.
(c) Cooked rice and lentils (any kind) are especially good dehydrated.
(d) Preparing a good dehydrated meal is time consuming (just like preparing any good meal) so plan ahead! Buy stuff when it's on sale, cook extra quantities of meals, and dry them for later. When summer rolls around and you need a couple of weeks supply of dehy food, you won't have time to do all the cooking and drying.
For recipes, Mexican and East Indian cookbooks are good places to look, but you can find ideas in many other places too. Pasta with "real" tomato sauce (home dehy) is so much better than store-bought you'll never go back. Don't be afraid to experiment!
