Hi Doug...welcome to the guitar obsession!! Sounds like you are on a good path.

I would say keep marching forward, but keep at practicing those chords and switching between them "in time". Being able to do that is your first step to playing real music!

Yes there is some repetition, so things you may have missed will be revisited. Strumming and switching chords is fundamental, so you want to keep that in your practice routine until you have it down.
