Playing By Ear Help

[sonnyz4]

Hey guys,

I'm going to be in the Mr/Miss Asian scholarship pageant at the University of Oklahoma.  For my talent, I'm going to play a medley of songs.  I've figured out two of them by ear, but I'm struggling on the opening piano part, and last chords of my medley. 

Here are the parts:

&t=0m17s
(just the first piano part)

&t=2m18s
(I'm looking for the chords the strings are playing, and the piano notes.  I think its like C#m or Cm, and D#m or Dm)

Thanks so much!

I'll post a video when I perform it March 30th!!!
