I think that that Hal Leonard series goes best with a teacher's guidance. The reason I say that is that the method book starts out pretty easy and if you don't have someone there to critique you and help you with your initial technique, you might just zoom through the exercises without doing each one right with good technique. With the teacher you can move through the books at a good pace, but also not just slop through it.
I know what it is like to blow it all finishing the basement, but I think that the early investment in the lessons will be more than worth it.
A small example of what I am saying happened in one of my lessons where I was playing something fairly close to the beginning of the book ~page 40 or so. I practiced through the week and was feeling pretty good about what I was playing. When I went to the lesson, I played the exercise for the teacher. He noticed that I was doing something really weird with my fingers that I didn't even realize. He pointed it out and we went through the exercise again. This time I paid better attention to what I was doing in that spot. Voila it nailed a really sloppy fingering early on before it became a habit.
I was doing stuff on my own prior to having the teacher and now I have noticed that my pace of progression is much better.
It is totally possible that you have different aptitude than I do, but I thought I would share my thoughts.
