I've never brewed that recipe. IIRC, its fairly high gravity right...something around 10%?
If you have hit the final gravity (1.000 or lower sounds right) you can just leave it. You probably didn't need to add more fermentables, but I don't think it will hurt anything, especially if you are looking for a slightly sweeter cider. It might ferment that out too however.
If you can't get into a secondary vessel like the recipe describes until Monday, no worries. You could probably let it sit for 2 or so weeks before doing anything with no problems.
