Yes, G# is a #9 in an F7 chord.

No, I have no problem with seeing Ab then A natural in a melody. If it's in the same measure, you must use a natural sign on the A natural. If the A natural is the start of the next measure, I might use a courtesy accidental natural sign.

Can you give us enough of the chord progression, along with the melody notes?

Although as I mentioned I like sharps in ascending lines (G# to A) I can't give an opinion without the full picture.
