Audition Help?

[cubinicano]

So I'm going to audition for FAU's commercial music department to attend the university either this fall or spring. And there are some auditions requirements which are:

# Two Pieces of contrasting styles (latin, swing, ballad) including one jazz standard (no original or rock songs; two jazz standards preferred)
# 12 Bar Blues in F or Bb

* Melody
* Chords
* Improvised solo

And..

* Consistent melody by itself at any tempo
* Walking bass line over chord changes

Any suggestions as to what to play?

Keep in mind, I'm still pretty much a novice at my bass when it comes to this sort of stuff.
