Editing Data

I need some help thinking about this. I will be using Gravity Forms to allow online sign-up, and the form fields will be used to store member profile information. I have a couple questions about how to use this.

1. Is there an easy way to edit the data that is entered? For example, when viewing a single entry, is there and easy way to make the data editable?

2. Assuming #1 is possible some how, could I give a member access to editing their own information only?

I have thought of a couple ways of accomplishing this (not using Gravity Forms at all, just a simple PHP application to update the data), but I want to make sure I'm not overlooking something very simple to allow editing the data from the wp-admin when viewing a single form entry.

Thanks for entertaining a very broad, generic question.

Editing data - I have not yet gotten into using data from a form to create a post. I might have to look into that for another project. But, for this one, a profile page is filled out by a new member, and I will have a need to modify that data in some instances (like, they change their address, email or phone number.)

That's what I'm thinking about. Any thoughts? It's nothing i'm looking for you guys to solve, but I figure there's a way to do what I'm thinking about, I just want to do it the best way. If the data in the entry were editable, that would be the end of it (displayed data is editable, so if you change it and hit [save], for example, the data is written back to the database.)
