I think sheet mulching is the same as lasagna gardening. You can use coffee grounds, shredded paper, table scraps, or whatever you have (even dog-chewed beef bones), some wet cardboard to hold it in place, and whatever you want to make the top layer presentable, and not blow away in the wind. Right now I am stripping 75 year old wall paper off my house. The plaster walls were pasted with some kind of cheese cloth fabric and the paper was pasted over that. Its all organic material so its going under my cardboard in the bed Im making now. Sheet mulching is much like composting in place, but you don't have to turn a pile -- and lose all the heat and nutrients to do it. It is infact "slow composting".

Its important to use plain brown card board, not something with a slick finish. Some people have tested things like cereal boxes and they have a high content of mineral oil that you probably don't want in your soil. Printing is o.k. on cardboard-- it is likely soybean based ink.
Yes. You can plant right through the sheet mulch.
