Hi Greg,
I am releasing a new plug-in soon that is described here:
This will provide for storing the user’s answers into their “Meta Data” table, and can be shared by other forms the user is presented with.
I am a php coder, and fairly proficient with WP/GF, and without knowing more about your requirements I can only guess that your other items will need some custom code additions to support.
Perhaps someone else will have a better answer.
Feel free to drop me a note if you wish to follow up, I am a professional consultant in this area, and have been helping others recently with similar needs, which is how I happen to be here now 
Cheers
