Kelly,
Now that SailSF has supplied the specs, contact US Spars for availability. Beneteau also has a Standing rigging kit (complete) for the boat; the Beneteau part number is 458057.
I usually tension my rig at 10% of breaking strength. At 10% the wires "feel" tight and have no slack; however, 10% tension is fairly light. Many tension to 15% and serious competition boats are up around 20%. Bad news is that you are going to need a set of two Loos guages to tension the large and small diameter wires. Best advice on tuning the standing rigging for in mast roller furling is to keep the mast straight with minimal bend.
Good luck with the new boat; hope you enjoy it. Don't hesitate to reach out if you have questions / problems.
