Different individuals require more instruction on different topics. chords may come easy to a person who has high difficulty with any lead picking at all, etc.
All the things Ben teaches need to be learned eventually in my opinion. My suggestion is to work most on what you understand or can accomplish the least if you really want to improve and have the patience for it. You are the only one (other than a personal instructor or someone you play with regularly) who really knows what you have the most trouble with; work on your shortcomings.
I don’t see an ordered structure of what to learn next doing anyone a lot of good as it becomes tiresome and depressing when you get hung up on one thing before allowing yourself to learn something else that may come easier and build confidence (which is needed form time to time also).
I suggest spending the majority of time on what you feel you NEED to work on. Then, work on what you Want to as the need arises to keep your spirits up and get some enjoyment form the process.
That being said I do suggest learning chords, chord progressions, and rhythm (to give understanding of song structure) first. One might play far differently behind a fiddle break than they do behind a guitar break or vocal verse or chorus. This also helps with learning more songs that can be played and speeds up the ability to play with others. Knowing a great lead break to a song is useless if you don’t know how to play all the other parts of the song, but if you can understand the rhythm and chord structure, you can jam with others and the leads and fills come much easier.
Optimally time should be split between learning and “perfoming”. Yes performing…recording self, playing with others, attempting to play with recordings, ect. Just as switching to a different lesson for a while can add new interest to learning, the “performing” side of things adds new dimensions to to your perspective of your own playing and can help you decide what to work on next for yourself.
