Blog layout options plugin?

Hi. I have a site with a theme and the layout for "Blog" type pages isn't good.

I'm talking like a index page that has all the posts listed.

Is there a good plugin for something that would give me layout options for this? I mean basically I'm just looking for a verticle listing, with each row having a picture, a <p> of text and a link to the post I'm referring to.

thanks,

John
