My son Kane is 9 months old and has about the same situation as you posted.  He is an absolute doll with so much character and personality.  He eats like a champ but occasionaly gags a bit.  He is in physical therapy for hypotonia and only is behind in his upper body strength.  I have a niece (non-noonans) who just had a very small espohagus that caused the same eating issues.  She got her adnoids out at about 7 and bam! all the problems were gone.

 

I am an information junkie and can find very little out there, any guidance would be appreciated.
