I applied directly to Eva Air. Once I had everything together, which took some time, I DHL'd the application with documents to Taipei. Worst part of the whole process is getting all the documents, letters of reference and certificates together. I hear you can also go through direct personel. Not sure how it works, I am guessing, but they probably just get a finders fee for getting you to apply, then I guess you are employed directly by Eva Air anyway.
