After a lot of effort, I found the answer, here is a solution for those stuck in the same position.

This goes in your plugin page where you are getting posts for a user etc.

<script type="text/javascript">
    $(document).ready(function() {

        posts = 8;
        author_posts = parseInt(<?php echo $author_posts; ?>);

        $("#link_selector").click(function() {

            // alert('posts - ' + posts + 'author posts - ' + author_posts);


            if ((posts - author_posts) > 3) {
                $("#link_selector").text('No more posts!');
            }
            else {

                var category        = '<?php echo strtolower($category); ?>';
                var id              = '<?php echo $blogger_id; ?>';
                var firstname       = '<?php echo $firstname; ?>';
                var surname         = '<?php echo $surname; ?>';


                // alert(posts + category + id + firstname + surname);

                $.ajax({
                    type: "GET",
                    url: "/wordpress/wp-admin/admin-ajax.php",
                    dataType: 'html',
                    data: ({ action: 'loadMore', id: id, firstname: firstname, surname: surname, posts: posts, category: category}),
                    success: function(data){
                        $('#ajax_results_container').hide().fadeIn('slow').html(data);
                        posts = posts + 4;

                        if ((posts - author_posts) > 3) {
                            $("#link_selector").text('No more posts!');
                        }

                    }
                });
            }

        });
    });

    </script>       

Then in your theme's functions.php, put your function to do your ajax request:

function loadMore() {

    $blogger_id = $_GET['id'];
    // get your $_GET variables sorted out

    // setup your query to get what you want
    query_posts('posts_per_page=' . $posts . '&author='.$blogger_id);

    // initialsise your output
    $output = '';

    // the Loop
    while (have_posts()) : the_post();

        // define the structure of your posts markup

    endwhile;

    // Reset Query
    wp_reset_query();

    die($output);

}

Then, just after the closing of your function, put in the action hooks

add_action('wp_ajax_loadMore', 'loadMore');
add_action('wp_ajax_nopriv_loadMore', 'loadMore'); // not really needed

That's it!
