This is only the 901 course. He also has the 902, Network+, Security + and some practice tests. I bought them all as it's my plan to finish them all

EDIT: Updated link to passport book

I used the Mike Meyers Passport A+ book along with Professor Messer (youtube) for that as well. Those along with some practice exams/studying any wrong questions will give you a better understanding of the fundamentals of computers/operating systems and how it plays a role in a modern environment. Also it just helps with better studying habits.

I also suggest to be hands on while reading the book for some sections (like when they show you the inside of a desktop, have an unused/unneeded computer available so you can tinker around). Be hands on and write extra notes in a note book so you can really take in what you're learning and begin to apply what you learn on a daily basis.

book

I would read CompTIA A+ Certification by Mike Meyers. It will explain most of the basics and help you with your job.
