You don't have to work your way through these exclusively before trying anything else. In addition to the fundamentals try the links that were provided and as you become more familiar with the site pick a few more to add to your practice schedule.
As a beginner myself thats what I did and am doing. Don't be afraid to go back to previous lessons in the fundamental courses either. I got stuck and struggled on the chord changes and didn't progress at all for about 2 weeks. Then I skipped ahead but always kept those hard lessons I was struggling with in my practice schedule. So instead of being stuck and standing still I worked on chords plus I kept moving forward.
You have found the best place to be in my honest opinion. Not only are the lessons and instructors here second to none, but the folks here on the forums are always eager to help and all are some of the nicest people I have ever "met"
Good luck and keep at it. Things that feel "funky" now you will do soon without even thinking about it,
