How to change the width of menu 2

Hi guys,

I am a relative newbie and am a little stuck. I can not seem to find how to change the width of my cat menu 2. I only have 3 menus needed but unfortunately the actual nav bar stretches across the entire site and I would like to shorten it to span just the three menus. swimtoslim.com

I am also having difficulty with my polldaddy polls plugin which is not working in my sidebar.

would greatly appreciate some advice on how to fix these problems.

thanks,

guven.
