Just a suggestion to help pull things together.
When you practice a tune try this process:
1) Pick a tune and beginning key!
2) Play an intro. Don't know an intro?

Oh boy, then you need to learn a couple intros.
3) Play the melody for a chorus.
4) Comp the chords in the tune for a chorus.
5) Improvise a solo over the chords in the tune for a chorus.
6) Play the melody for a chorus.
7) Play an ending. Don't know an ending?

Oh boy, then you need to learn an ending or two.
8) Move the tune through the circle of 4ths or 5ths and repeat steps 2-7.
9) Develop a repertoire of tunes.
Do this for a long, long time.
(You could also play a chord melody for step 3 or 6 if you like and can manage it.)
