Metal in the microwave is bad. It will spark. Sparking/burning metal is bad as it releases bad fumes from impurities in said metal. Also sparks can lead to fire.
Paper towels are fine so long as there is no spark or they are wet. Microwaves need to have moisture, as the microwaves excite the water molecules which creates heat. Running a microwave without moisture is bad for the microwave.
Most food contains water. That's why microwaving food usually dries it out, especially the outsides. (Cooks outside in as the water molecules on the outside of the food absorb the energy and heat up)
The more exposed surface area you have the more even heating. Cut up food, arrange in a circle, and rotate it half way. Most microwaves rotate/move for this reason, but what I said helps. It also helps to leave it in the microwave for a few minutes for the temp to even out through conduction (hot areas of food heat up cold areas through contact) and convection (hot air heats up cold areas of food).
If you microwave food that has a similar diameter/length to a multiple of the wavelength of a microwave it can spark and burn. It focuses and amplifies the energy. Grapes can do it. I've had popcorn chicken do it if it touched another popcorn chicken. Pretty crazy as the food will burn like an electrical fire. (Don't do it)
The black "screen" that is in the window is there to protect you from the microwaves. They block them from leaving the cook area, and that's why they don't run with the door open. Don't run a microwave with it busted out. You are 70% water, and radiation is bad... m'kay?
