Not OP, but I've gone through the E3 process a couple times. First as a change of status, second as a new applicant. You have to prove two things: 1) the job is a specialty occupation, and 2) that you possess the necessary skills and qualifications for the position. The rest of the application is a walk in the park.
Regarding the general perception of E3, I've found that very few people in the U.S. know about the E3 visa class. You may need to educate your employer a little.
