There are countless paths you can go down, so I'll cover two of the most popular.
"Traditional" Jiu Jitsu
Brazilian Jiu-Jitsu: Theory and Technique by Renzo Gracie and Royler Gracie
This book covers BJJ from the most simple techniques, to the more advanced stuff. You not only learn positions and submissions, but little intricacies that help you hold the positions, and transition between them (ex. which grips to use, how distribute your weight, etc.) The ability to, as you say, "link techniques together" is essential, and Renzo and Royler are two of the best to ever do it. They go over all the names of common positions and techniques. There are two down sides to this book; it's gi heavy. If you're planning on fighting, you'll need to learn exclusive nogi techniques elsewhere. The other down side is the defensive techniques are limited to defending against stupid moves (untrained folk), and defending against the Gracie techniques you just learned. (so good luck defending against our next author, Mr. Eddie Bravo)
10th Planet Jiu Jitsu
Mastering The Rubber Guard: Jiu Jitsu for Mixed Martial Arts Competition by Eddie Bravo
This book couldn't be more different than the first one I mentioned. Eddie Bravo developed his own BJJ system, centered around the rubber guard. Eddie goes into depth as much, if not more so than the previous book. He covers positional changes, technique flows, and of course unorthodox submissions. Eddie has his own naming system that is overwhelming at first, but you'll get used to it. Two down sides to this book: It doesn't cover "everything you need" for BJJ. You will learn rubberguard and a few other things, which are foundations for 10th Planet BJJ. He has more advanced books to further your knowledge. The other issue is the book is old. Eddie is constantly developing his system, so rubber guard has been tweaked and improved countless times since this release. Eddie has no problem letting his students add to his system. If you use this book, be sure to research the techniques on YouTube for updates.
All in all, there are a lot of great books out there, but these are two of the best. Since you have a Judo background the first book I mentioned will be much easier for you, as you won't have to learn as much new terminology. You really can't go wrong with either, just supplement your training based on the downsides of each that I mentioned. But remember, you can't improve by just reading books, watching videos, and drilling, get in the gym and roll!
Edit: Since I mentioned YouTube I'm also going to add one of my favorite YouTube channels, Stephan Kesting. He provides excellent step by step technique lessons, as well as plenty of BJJ philosophy. Great place to look for techniques for any level BJJ practitioner.
If you want a more "formal" instruction, Ryan Hall is widely regarded as one of the best in the BJJ instructional video game. Much of his content is on YouTube as well. His stuff can get pretty advanced, so it might not be the best place to start for a beginner.
