Hopefully, you have your books now. With those four books, you could have an entire carreer in magic and never need to purchase any other book or item in magic. Seriously. Of course, you'd probably want to pick up some sponge balls, cards, rope, etc., but those four books are all that you'd honestly ever need.
With Alkazar, just read it straight through and learn a couple of the tricks. It's easy to read and you can kill it in a day or two if you really want to do so.
With RRTCM, it's written for you to read it, page by page and work through all of the material. However, Opie (a member here at TM) put out a guide that you may find useful. Just
click here if you'd like to peruse his guide. Certainly can't hurt, eh?
With Bobo, it is encyclopedic. I would point you to the Bobo study guide that I published on these pages. It will help you to keep it in perspective, because it's easy to look at the expanse of what is in Bobo and simply put it on a shelf and forget about it (you'd be surprised by how many people do exactly that). For the Bobo guide,

Wilson's is also encyclopedic. Try to choose a couple of things that specifically interest you and page through that section. Maybe rope interests you - you can put together a strong rope routine using only the material that is supplied in the rope section of that book. The same for sponges, balls and all the other sections that it offers.
Most of all, take your time and learn what is there. I cannot say it enough times - those four books give you everything that you'd ever need for an entire carreer in magic.
