Meats do not last long in the refrigerator. Only about 3 to 4 days if it is raw. Then 1 to 2 days longer if cooked and placed in an airtight container. You should always cover meats when stored in the fridge.

Bacteria can form on food left out after an hour. It is best to refrigerate cooked food as soon as possible to prevent this.

as long as you keep the pork chops refrigerated, they should be find to leave overnight until the next evening's dinner. if you have the time actually, marinating for at least 12 hours lets a lot more flavor absorb into the meat.
It usually depends on what you're marinating them in but, I would say about 10 to 12 minutes.
