I strongly recommend liking ¡Viva Vaquita! on Facebook: http://www.facebook.com/vivavaquita. They have great posts, links, and contests. If you already liked them, then you probably know about the music video for Garage Rockstars Guadalajara’s song “Desapareciendo,” dedicated to the Vaquita: http://www.youtube.com/watch?v=XF1ItEQ_6TE.
Also, if you plan on going to Mexico (particularly around the Vaquita’s range), think about visiting these businesses that are owned/started by fishermen who changed livelihoods to help the Vaquita: http://www.cedointercultural.org/images/stories/list_of_the_pace_vaquita-reserve_support_projects.pdf.
