There are some nice looking themes at themeforest.com. Really you should be able to take any theme, even wordpress themes, and quickly convert them to erb/haml/etc templates. I would guess you are just looking for a nice layout. A Wordpress themes would give you the structure of the page, plus the css. You'd just have to fill in that structure from your rails code instead of wordpress.
