            if ($wp->query_vars[$this->namespace.'_p'] == 1){
                $args['posts_per_page'] = 10;
                $args['offset'] = 0;
            }else{
                $args['posts_per_page'] = 40;
                $args['offset'] = 10;
            }

the meaning of that code is: if you are on page 1 of the pagination, show 10 posts per page, start with the first overall post. if you are not on page 1 of the pagination, show 40 posts per page, start with the 10'th overall post (i.e. skip the 10 that were displayed on page 1.)

 

this was done so that the first page shows less total information, resulting in pagination with two different number of posts per page, i.e. 10 on the first page, 40 on all other pages. you would not add code for each possible page. you would only change that code if you want to alter the number of posts per page, i.e. to make all pages have the same number of posts per page or to change the number of posts on the first page to be for example 5, while the number of posts on the rest of the pages are 40 per page.

 

here is the documentation for the $args parameters (the Pagination Parameters are about half-way down on the page)  -  http://codex.wordpress.org/Class_Reference/WP_Query#Parameters

 

if your pagination isn't working, there's some other problem then the specific code in your post above.
