Learn the notes on the other strings. The D string is the same as the E but the musical alphabet letter notes are 2 frets higher. Again on the B string but 3 frets higher than the D. the high E is the same as the low E.

Learn the notes on the A string, then you can use the octave method to get the notes 2 frets higher on the G string.

Done!

[quote=Beo420]3. how to move freely around the neck? How to interchangeably use different pentatonic and major scales and move around the neck so it sounds good? How to learn to improvise?

Learn to cover the fretboard with scale degrees. Start with Series 1 which covers one octave patterns. Series 2 expands the idea to 2 octaves.
