Pagination and Loop for Custom Post Type

Hi,

I’m currently using Magic Fields2 to use Custom Post Types, WPML for multilingual and few others which are not related to my problem.

I would like to render posts on the blog page, with 8 post per page (currently, I use 1 to do tests).

I had some fields to the original post type and so I now have to use it as a custom post type.

I’ve got some difficulties to do an effective pagination which lead to something else to a 404 page.

I’ve read many supports on this subject, as post-1 and post-2 and few others but I can’t find the solution.

Here is my code currently, but It doesn’t stop moving to find a solution.

My page where this code is written is called “blog” and the origin post type is called “post”.

<?php

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$wp_query = new WP_Query();
$wp_query->query('post_type=post&posts_per_page=1'.'&paged=' . $paged);

if ($wp_query->have_posts()) :

while ($wp_query->have_posts()) : $wp_query->the_post();
?>

<article>
 MY CONTENT
</article>

<?php endwhile; ?>

  <nav>
    <div class="nav_post"><?php previous_posts_link("&laquo; Précédants") ?></div>
    <div class="nav_post"><?php next_posts_link("Suivants &raquo;") ?></div>
  </nav>

<?php endif; ?>

Does someone would help me to figure out how to implement a good pagination (numbers/previous-next) ?
And after this first step, how to setup this page/2/ without to go on a 404 page ?
