For lists of good new webfonts, try MyFonts’ monthly ‘Rising Stars’ newsletter: http://webfonts.info/webfonts-know-how/november-rising-stars...
Also, Typographica makes an superb list every January: http://typographica.org/features/our-favorite-typefaces-of-2...
And for some inspiration, you can always check the most popular fonts at TypeKit: https://typekit.com/lists/favorite-fonts
However, I've found that the WebType service actually has the best text fonts for small sizes. Headlines are nice, but what really matters is your <p> text. Their RE (Readability) series is excellent for small text.
I'm personally using Benton Modern RE and Benton Modern Sans RE for smaller sizes, and Benton Modern Display for <h1> headlines.
They should make that easier to discover.
