The answer depends on your goals. If your goal is mainly to solo, then it's not a bad idea to learn some of the scales. The only problem with learning this scale so early in the game is not knowing how or when to use it. I generally advise a student to have a good understanding of chords and chord families, so he or she can learn how to use that scale to solo to a song.
There is a common misconception that an electric guitar player doesn't need to know chords. The very opposite is true however. Electric guitarists need to know basic chords as well as variations of chords so that he or she can use the entire fret board in a given song.
Every instrument in a band is tied together at some level, so it's very important to understand what is happening musically so that you can understand what your role in your instrument. The acoustic guitar player has a different role than an electric guitar player. The soloist must be very aware of the music that is supporting the solo so he or she knows when to get loud, play faster, or drop out.
While there is an endless amount to learn, there are certainly systems and methods in place that will not only guide you in the right direction, but also help you measure your progress. It's also important to set your goals. The Guitarmann Electric guitar series will show you how to solo all over the fret board, but keep in mind that music is a team sport. There are few guitarists in the world that make a living by soloing all by themselves.
If you're dead set on learning electric right off, then balance that with learning the basics of guitar. Work through a few Guitarmann Essentials lessons or Beginner lessons (depending on your level), and then mix in a few Guitarmann Electric series lessons to keep you motivated. Most importantly, be patient. You will learn what you set out to learn.
