For that genre you can set the check list that will include
1. Chords/Progressions/Scales
2. Performing techniques (right/left hand)
3. Rythmical, speed excercises
4. Songwriting (if you need it)
5. Improvisation (if you need it)
While you're getting better - you'll discover new areas to add to your check list to move forward)))
Good luck!!
