I highly recommend at least learning the pentatonic scale. It's very easy, and it's the basis for most rock and roll lead guitar. If you're in the right key, you can noodle around on the pentatonic along to songs, and it will generally sound decent. For learning chord progressions, learn all the basic major and minor chords, then experiment with putting them together. There's a lot of joy to be had in that simple exercise, and with practice, you'll start to get an intuitive sense about it. Once that starts to make sense, you can start looking into the more unusual variants on chords. Also, lessons can be fun, especially early on, because a teacher can point you in a specific direction for practicing that will cause you to grow.
