The upper G clef shows just the melody, for a singer. Those notes are also included on the lower G clef. So just play the F clef and the lower G clef.
I'm not sure what you're asking about the coda, but in case you're asking when to play the coda, the answer is given by the instructions "D.S. al coda" given at the end of the top staff on page 6.
Play the music through the first ending and repeat. On the repeat, play the second ending and play until the end of the measure marked D.S. al Coda. "D.S." is short for "dal segno" and the whole phrase means "from the sign to the coda." (Coda means "tail".). So you go back to the dal segno sign, which looks like a big squiggly S with a diagonal line through it. It appears at the beginning of the first measure of lyrics at the bottom of page 1. Continue playing from the dal segno sign until you reach the coda sign, which looks like an upright oval with a plus sign through it. It appears at the end of the first measure at the top of page 4. From there, jump to the coda on page 6 and play to the end of the coda.
