NEW GRAD wants ER!!!!!

Hey guys,
I am in my SENIOR year of nursing school, Accepted a Scholarship, so I have a Job right after graduation at a hospital for 2 years. I externed in a local ER over the summer and absolutely LOVED IT, when i compare it to floor nursing I never want to go back to it!! So here is my dilemma, i really want to work in this Hospitals ER, I can request to get an Interview, which they start doing in january, but it doesnt mean I automatically get the job... and If i dont get the Job i want they put me anywhere they need me... So I have some questions as to what I should so... I was thinking Maybe sometime this week going over there and talking to the Nurse manager of the ER.. should I call first or just show up? and what can I do to sell myself better, so I can convince her/him to hire me as a new grad with no experience.. I am not lazy, I am HUNGRY to do anything and everything, i love the quick Flip of helping people getting them in and out, i have a great personality... but what can make me stand out as a NEW grad compared to others... I really want Emergency medicine!!! If anyone can give me some advice It would be greatly appreciated!!!
