That's great, thanks for your help! I guess if I wanted the option of
additional parameters I could do something like:
$html->link($category_name,array('controller'=>'Blogs',
'action'=>'index', null, 5));
function index($category_id = null, $tag_id = null)
Does that look right?
Also, do you know if this will work with pagination and habtm relationships?
After some googling this morning around my problem, I came across this a few
times as a kind of known issue, so wondered if perhaps it was related? My
categories and tags are in habtm reference tables.
Thanks again for the advice.

If you are only ever going to filter for category_id, you could do this:
> $html->link($category_name,array('controller'=>'Blogs',
> 'action'=>'index', 3));
Then change you index function to:
function index($category_id = null)
...and then check for a non null value later in your code when you do your
data extraction.
