Issues styling blogroll after moving to 2.1

Hi,

After two years of always finding answers in the forums I come to an impasse! My thanks in advance for those who jump in to help me out.

After migrating http://www.mars-hill.co.nz from wp2.0 to 2.1.3 I have managed to get my blogroll up and running again, but am having lots of trouble styling it. You can see the blogroll in the grey sidebar at the bottom right of the page.

If I use

<div class="block">
<ul class="counts">
 <?php wp_list_bookmarks('limit=5&orderby=rand'); ?>
</ul>
	</div>

I get unsightly extra lines. If I replace ul with div then I get an square-bulleted list, even though I can’t find such a reference in my css file.

To resolve, I’d appreciate if someone could tell me what calls to css the new wp_list_bookmarks tag makes, since I can’t see it in the documentation
OR
If someone could help me with some css-foo to right all the wrongs!

Thanks again!
