While it is normal for plants to adjust after repotting, it sounds like your may be in shock or suffering from improper watering. Have you allowed the plant to dry out sufficiently between waterings? Perhaps it isn't receiving enough water? Put a bowl of water under the plant and wait a couple hours. Is there still water in the bowl? If not, then the plant is in need of more water. If there is still water in the bowl, pour it out as the plant is getting plenty of water and needs to dry out.

With houseplants, you should not be watering on a schedual, but rather checking on a schedual. Water the plant when just the very top of the soil is dry.

It sounds like it may have a bit of a fungus, which is causing the black spots and yellow leaves. Treat the plant with a fungicide. Since you know now that it is prone to fungus in that spot, you may be better off setting it on a pebble tray filled with water rather than misting to help with the humidity.

You probably do not need to repot it at this time. They like to be a little root bound.

You can make one quite easily. Get some sphagnum moss (you can find it at craft and florist shops). Place the moss on a appropriately sized board for your plant. Use fishing line to wrap around the moss and secure it to the board.

Swiss cheese plant is easy to prune and very forgiving about how it is pruned. Try not to rune more than 1/3 of the plant in any one season, but other than that, just use a clean, sharp pair of scissors or pruners to cut away the growth that you do not want. It makes it look cleaner if you cut near the junction of a leaf and stem, but the plant will be fine no matter where you prune.
