Re: Helms 25 Rolling boom question.
A gentle terminology correction... the MAIN SHEET leads from the boom to a traveler in the cockpit. A boom vang is a different beast altogether - hopefully you have one, leading from a few feet aft of the gooseneck to the base of the mast at the deck. This limits boom lift and prevents an accidental 'goose-wing' gybe.
The original roller reefing boom setups generally left a lot to be desired and most have been converted. You are correct in that with the current setup you cannot use the roller feature, assuming it still works. One would also assume that some sort of jiffy/slab reefing was set up when the mainsheet and traveler were moved/modified.
As to the running rigging lengths, depends on whether or not lines are led aft or on the mast still... take a long (30-50) foot tapemeasure and run it up with a halyard to get the mast height.. then figure twice that plus and distance aft, plus a few feet just in case... you can always trim them later.
