Sugar? Use either. Same thing, different source.
Jelly bag or cheese cloth? Use either. I've got jelly bags because they came with rings and tripods that are easy to hang over a bowl to catch dripping liquid. Cheese cloth works just as well. Use a couple of layers though. Just tie the corners and hang it from a cupboard or something so it can drip into a bowl. Don't squeeze either as you'll get cloudy jelly that way.
Leftover liquid? Can more jelly.
edit to add - With the leftover liquid, cook it a little longer to thicken it up and use it as syrup. Would be a great alternative to maple over pancakes or would go great over ice cream.
