How to pass user Meta data to Pre-Populate Reservation form

Ok, I'm having a tough time making the final connection with pre-populating of a reservation form ( http://www.pairadicetravel.com/reservations/ ). This is what I have so far.

1. Using Gravity Forms User Registration Add-On to replace default wordpress register function. (works great)

2. Created a register form that gets the info that I want to populate in another form. (http://www.pairadicetravel.com/contact-us/) Works fine.

3. In the reservation form, I've added all the parameter names to the fields that will be pre-populated. Those names match the names of the same fields from User Meta.

What I want to happen is once the user registers and provides the needed information about their room preferences, it's stored on their profile. It's currently doing this step. Next once that user logs into the site to make a reservation that meta information is populated into the form. I've tried going through the help pages, but get lost on the parameter names. Can this be done by shortcode?

Thanks.

Thanks for that help. That worked, but not on Drop Down items or items like the Address and full name. How do I set the default value for those?

Following the instructions for short code version would i just use this:

[gravityform id=3 name=UntitledForm title=false ajax=true field_values='prefix={user:prefix}&first={user:first}&last={user:last}&suffix={user:suffix}']

to pull the values from the signed in user profile?

Hello. Can you provide me on instructions on how to proceed? Thanks.
