Is it possible to get permission to access a Facebook user's User ID without having them leave your webpage? Is an iframe with the permission dialog the only true way to accomplish this?

You can use the Javascript API to Extend Permissions. Lets say that you have already request the Email permission, If you pass a new permission to the login button, the User must approve the new perm also.
example Login Button:
<fb:login-button perms="friend_likes"></fb:login-button>
example FB.login()
function fbAuth() {
FB.login(function(response) {
if (response.authResponse) {
alert('User fully authorize the app.');
} else {
alert('User canceled login or did not fully authorize the app.');
}
}, { scope: 'friend_likes' });
}
then you can call it with an onclick event or any other method you want:
<a href="#" onclick="return fbAuth();">Login</a>
