1) As others have said, learn some jazz standards (chord changes and melody). You'll start to see some common elements (and hopefully have some fun!). As i recall, my instructor started with "All the Things You Re" and "Autumn Leaves".
2) Learn a
system of chords, triads, arppegios (and scales) fingerings to allow you to
focus on the music vs. mechanics.
One of my old guitar instructors (Rolly Brown) from twenty + years ago has put together an excellent series of instruction courses that will take you through the "nuts & bolts" of jazz chords, melody and aspects of improvisation. Looking at the syllabus, it appears to be similar to what he did with me many years ago (particularly the two nuts & bolts lessons).
