Can I setup Twhirl to only show my tweets and @replies or DMs to me?

Since I use Twhirl to support a OSS community, I want to be able to follow all those that follow my account (because it's the right thing to do) but I want to filter the noise that comes through. By only showing my tweets and @replies or DMs to me, I can use Twhirl to focus on what I've tweeted and replying to people that are asking for assistance.
