Custom User Profiles

OK, I'll preface this by saying that I'm a total n00b with Zen Cart. Perhaps I'm just missing something here, but is there a way to either:

a) Customize the user profiles and add required fields?
b) Create a form that is required, stored, and searchable for each order?

I'm not too picky as to which option works, as long as I can store more detailed information about my users. Here's a brief example of my application:

This installation of Zen Cart will be used for course registration for a Nursery School in Manhattan, NY. During the application process, a lot of information is kept on file, including dietary concerns, medical issues, a list of authorized people who can pick up the child etc. Bottom line, there's a lot of general info that has nothing to do with the product itself, however it still needs to be collected.

I would greatly appreciate any advice that any of you can give me.

Mike, have you found any info on this? We are looking at a need for what amounts to a registration form that takes money which sounds like the same thing you're needing. We have used Zen in the past so we'd love to use it again for this project!
