That message is normal when you're setting up your Facebook Application and JFBConnect for the first time. Some profile fields require additional permissions from the user to allow your app to import that data. Birthday and their feed (to get their last status update) are some of them.
As noted in the message, that notice is only shown to you since you're the developer. You can test registration and the data will import. Once it's working how you want, you'll need to go through the Review process. That is where you provide some information to Facebook on why you want to import specific data. Once Facebook approves your review request, then those permissions can be granted by any users of your site.
Facebook is changing rapidly right now. In light of the privacy issues last month, they are restricting more profile data. It's constantly evolving, but we're working hard to update JFBConnect and make it more flexible as Facebook (and other social networks) make changes. For more details, see our recent blog post,

For the Review process, you can initiate that in the
Facebook App Developer Area
after you've tested.
I hope that helps explain,
