Small style changes, where to do?

[b]1)[/b] At the bottom of the page, at categories and manufacturers, it will automatically be broken off at 10 pieces for the word more... I would like to limit this number to, for example, 5. I just can't find where to do this.

[b]2) [/b]I would like to limit the number of characters displayed for a product on the product category overview page. For example, that a max. number of characters is displayed and this is then broken off with ...

Now I can type text endlessly, but then it gets messy. I do want it to be fully displayed on the product page itself. Is this possible in an easy way?

1. You can edit includes/boxes/box_site_footer.inc.php (checks are at line 26 and 52), change from 10 to 5

The views are
1.includes/templates/default.catalog/views/box_site_footer.inc.php

2. includes/templates/default.catalog/views/listing_product.inc.php
