I haven't seen that Heller kit for a long time, but as I recall it represents a three-decked French ship-of-the-line from about the time of the American Revolution (or a little earlier). There are quite a few good books about rigging of that period - but most of them (at least the ones in English) deal with British practice. Off the top of my head I can think of two that would be directly relevant to this particular project:
1. Jean Boudriot, The 74-Gun Ship. (Original French title: Le vaisseau de 74 canons.) This is a four-volume masterpiece, covering every conceivable detail of a two-decked ship-of-the-line of the period. (The rigging of two- and three- deckers was virtually identical.) Vol. 3 is the one that covers the spars, sails, and rigging.
2. Karl Heinz Marquart, Eighteenth-Century Rigs and Rigging. Of all the rigging books, this is the only one I know that attempts to be truly international in its coverage.
Unfortunately both of these books are quite expensive - and rather hard to find in the U.S. But if you're within driving distance of a good library it may have them - or be able to get them through the Inter-Library Loan service.
If you aren't planning on doing a really detailed job of rigging (this is, after all, a pretty small scale), you may find a more basic, generic source about rigging perfectly adequate. The best place to start, in my opinion, is George Campbell's old classic The Neophypte Shipmodeler's Jackstay, which is available as a very reasonably-priced paperback from Model Expo. (Even cheaper used copies can be found on the web.)
Hope that helps a little. Good luck.
