New Link Names

Hello,
Here's the link to my site I am still developing www.langewinery.com/blog

I'm now starting to delve into changing the HTML and installed Firebug to help me out. When I add a new link to the Members Of category, the name placement below each logo/link is different. I found the text in the HTML and can remove it completely.
My question is how can I center, move, or change the look of the text?

Thanks!!

Tim
