Theme CCK teaser - Explained with pictures!

Hi,

I'm having trouble theming a teaser CCK node I created

This is the configuration of the node:
http://i26.tinypic.com/28bfc55.jpg

And this is my Teaser view:
http://i26.tinypic.com/i5wya0.jpg

So I need an answer for this two parts:

What I want to do:
1. Move 5 star to the bottom (I found that this can be done with $node->content['fivestar_widget']['#value'])
2. Put the taxonomy next to each other, separated by commas, and not in the lines.

The way to do it:
Should I do this by using the Template of contemplate?
Should I create a new tpl file to show the node the way I want (which tpl file name and how to specify teaser?)

Any other tips would be great!

Thanks!

Andy.
