GD Star rating customization

I have installed GD star rating, and am only planning on using it for comments. What I want is to
1) Change the summary rating to totals for each
2) change the thumbs up icons to ‘Agree’ and conversely, the thumbs down to disagree.

So i want it to look like this:

Agree(###), Disagree(###)

Is this possible? Or is there perhaps a better plugin to do these things?
