Alpha 43, you've discovered one reason why so many serious ship modelers refer to Artisania Latina as "Artist in the Latrine."
Unfortunately I don't know of a good set of plans specifically for the Constelllation. The best I can do is to recommend some books on the general subject of ship model rigging.
One of my favorites is George Campbell's The Neophyte Shipmodeler's Jackstay. It covers a lot more than rigging, it's dated, and it's primarily aimed at solid-hull wood kit. But it contains an enormous amount of sound, basic information - and it's cheap.
There's one called Rigging Period Ship Models, by Lenarth Peterson. I don't have it, but it has a good reputation.
Here's a link to the book page of one of the big ship model suppliers, Model Expo: http://www.modelexpo-online.com/search.asp?SKW=cat1_KH&PAGLEN=20&STARTPAGE=1 . The books by Biddlecombe, Lever, and Murphy/Jeffers all fit your historical period (more or less), and should be quite useful. Remember: ship rigging changed a great deal over the centuries, and excellent books about one period are almost useless for another. Anderson's The Rigging of Ships In the Days of the Spritsail Topmast and Underhill's Masting and Rigging, for instance, are classics, but just about irrelevant to a nineteenth-century warship.
Hope that helps a little. Good luck.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
