Plugin for user self-management of data

I’m trying to find a plugin that will do the following:

— Allow registered users to submit a specific form (they must be logged in).
— Allow registered users to view only their own submitted form results.
— Allow registered users to edit their own submissions.

The form needs to contain a list of pre-configured items each with a checkbox preceeding it, i.e. class name, date attended and number of hours.

User needs to be able to check the checkbox to indicate that he has attended that class.

At the bottom of the form, there would be a total number of hours shown, which would be the hours associated with each checked item automatically added up.

It would also be nice if the user could add his own items to the list with class name, date attended and hours, just like the pre-configured items.

Anyone have any suggestions on how to go about this? Is there a plugin that would allow me to configure this or should I be looking at a custom post type? Any suggestions on a plugin that would help me build this?

Thank you for any suggestions!
