Sadly Biggs himself doesn't get a lot of story anywhere, he appears only briefly in Episode IV and after you re-watch it you'll understand why he has his Pilot Ability.

On the otherhand the X-wing books also continue Biggs story somewhat by introducing his younger brother Gavin Darklighter. (Who I think it would be cool to see as a pilot card someday.)
