Welcome to the Forum! You'll find lots of interesting stuff, and stuff that's valuable for your particular project, here. The inhabitants, as you'll quickly find out, are eccentric but generally harmless.
I'll second GeorgeW's recommendations on sources for H.M.S. Victory. The Heller instructions are miserable; the people who wrote them didn't understand how rigging works. It is, in most respects, a beautiful and accurate kit, but it contains some really remarkable errors - mostly of omission. The Heller designers apparently didn't understand, for instance, that yards are supposed to be fastened to masts. And the English "translation" of the instructions that comes with the kit is hopeless; it apparently was written by somebody who neither understood French nor had attempted to build the model. You're best advised to use the Heller instructions only as a guide to how the various pieces fit together, and rely on other sources for everything else - especially the rigging.
The Victory is one of the most thoroughly researched and documented model subjects in the world - the subject of several excellent books and at least four good, reliable sets of plans by outstanding draftsmen (Basil Lavis, R.W. Bugler, George Campbell, and John McKay). I agree with GeorgeW: if you need to pick one source, the one to get is Longridge's Anatomy of Nelson's Ships, which contains fold-out copies of the George Campbell drawings. (The title notwithstanding, the book is actually a detailed description of how the author built a model of the Victory, on 1/48 scale, from scratch.) The McKay drawings contain more detail than Mr. Campbell's, but Longridge provides a well-written, comprehensive verbal description of how to rig the model. (Those rigging instructions are almost as applicable to the Heller 1/100 kit.)
If you do a search on the word "victory" in this Forum you'll find several threads that will be helpful - including lots of posts by folks who are working on the same model.
Good luck.
