Well, other than presentational skills and showmanship skills, almost all legerdemain have no relevance towards each other at all. You could really learn in any order you want to.
You know what MY first DvDs were? NINJA 1, NINJA 2, and KARD KLUB. I gained decent-mastery over the pass long before I mastered the overhand shuffle. Why? Because the overhand shuffle and the pass has no relevance in method and many other sleights are like that too. It is extremely rare to come upon a sleight that is dependent on other sleight.
However, you'll still want to stick with the beginner materials as, the things like the pass take a very long time to master. However, the overhand shuffle controls is something that can be learned in a few days and you can already use that sleight for a multitude of tricks, effects, and routines, like, the Thought Speller trick in RRtCM.
If you encounter a DvD that teaches legerdemain but it says it's more intermediates and up, DO NOT BUY IT because, most likely, it'll require that you already have good knowledge of a wide variety of sleights and techniques.
If you want to learn one of those "One-Hit Wonder" effects, please, go buy it and learn it. It will (if it doesn't, it SHOULD) teach you everything you need to know to master that effect.
If you see a DvD you like with a "beginner" tag on it that you like, then go ahead and purchase as it should teach you everything.
Now, if your going to learn cards, I'd highly recommend that you purchase the Card College Series or even just Volume 1. It is so easy to learn from that book. It's like an english professor is teaching you magic on paper. The eloquence and the ease-of-learning is far better than any other book out there on magic. Please, trust me. Get that book.
Also, ever since I read a few chapters of Card College, everyime I open an old book to read and learn about techniques, it is SO muche easier to read because you'll have understand the lingo and termonologies for magic, you'll know exactly how each part of each finger is referenced, and you'll know which part of the deck is being referenced.
Card College really is a small investment for your magic career. Do yourself a favor and get that book.
However, if you prefer to learn more visually, then go ahead and get either Born to Perform, In the Beginning There were Coins, Crash Course 1, Mpdern Coin Magic DVD SET, and a few others.
