How to choose plugins to enhance the Daily Theme

I am just getting started. I have WP 3.0, the current version of BP and the Daily Theme installed. My site is not yet publicly available. It will be a humor site where our group of friends can share photos, videos, stories and comments. We will also try to support some local small businesses with a few ads on the site. Our objective is to create a fun place where we can share our observations about all the every day goofyness around us. (We all think we are funny). Can you suggest some plugins or additional widgets that could help us accomplish our goal? (There are so many to choose from).
PS; I like this Daily Theme a lot.
