Blog Posts by Category (again)

Hi, already been here once, thought it would be the same for my next issue, but it’s not and the code seems different to what’s in the Codex help files. Found a similar one, but changing anything just basically displays a link to my blog, which is just an endless loop.

I have a blog template with the following code:

//custom_blog_posts(array('post_type' => 'post'));
   global $wp_query;
   wp_reset_query();
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
	$wp_query = new WP_Query(array('post_type' => 'post','paged'=> $paged));

This shows ALL blog posts, I would like it to only show the posts from a certain category. (cat=8) However I can’t see what I’m supposed to change here.

Any help on this issue would help me a lot. ??
