if there's no self steering arrangement, and you'll be hand steering, then the last block in the sheet, where the tail of it comes to hand, could well be fitted with a cam cleat. Failing that, there will need to be some kind of cleat which is easy to use, such that the tail of the sheet will not foul the tiller. That's sometimes difficult to arrange with a transom- or sternpost-hung rudder.
For the first few reefs, no downhaul is needed, and the battens should drop under their own weight. When deep-reefed, the luff hauling parrel should haul down the upper luff satisfactorily, and you are left with the issue of what to do at the aft end.
