Dear Jepoy:
About the Bach, I agree with Mr(s). Walking, and must add: play anything solo but a
concerto. It's important to study pieces from this genre but it's very difficult to render properly with a piano accompaniment.
Mozart: what a wonderful choice. I love this piece. Remember that's an example of the "romantic" Mozart, so, let yourself go.

Schumann: to be very honest, I don't think his solo works are in a pair with his vocal, chamber and orchestral masterpieces, but anyone seems to love and play his music. I would for sure play some late Schubert, or Chopin, or anything instead. Again, I agree with what Walking wrote: a long romantic piece is a must.
Chaminade? Well...
Finally, it's cool to play local repertory, but don't forget the great masters of 20th century. There are several options, it's up to your skills and taste: Debussy, Schoenberg, Bartok, Prokofiev, etc, etc.
Best wishes!
