I think the Sklansky, Malmuth, Miller book is a fantastic first book... especially for live LHE. They sprinkle in some extremely advanced concepts that even some mid-tier mid-high pros don't understand. Its weakness is that it teaches you nothing about shorthanded play. In fact, you will get outright murdered shorthanded if you only go by this book.
I still think the Stox book is great even if it wasn't written by the most ethical person. I would make that your second book. You will be competent shorthanded, but you will not be able to hang with stronger mid-high pros.
From there, I would move on to the Deuces Cracked video series called "Relentless Assault" by Deathdonkey. It was made 12 years ago, but the top LHE players in 2008 would still be very strong nowadays. This video series will teach you how to take care of yourself shorthanded and introduce you to some extremely advanced concepts.
Next, I would watch "My Danish Luckbox" by Oink on DC for the first time. This is extremely advanced LAGTAG and outright LAG play. In my opinion, even Oink himself really had no idea how fantastic this series is. Any time I am feeling off my game in LHE, I watch this series again.
Finally, I would watch "Five's a Crowd" by Deathdonkey and MikeL on DC. This will fully school you on shorthanded play. At the time, Deathdonkey was an online crusher and MikeL was a live crusher. The two unique perspectives really meld well together in this series. I usually hate it when coaches spend enormous amounts of time on spots, but they make the most of it in this series and keep me entertained.
Solver work and studying bots is not really necessary unless you want to play in the highest games live or want to torture yourself playing in tough online games. The "cool kids" will tell you otherwise, but this old dork says you will be fine!
