New grad job interview

So, i have the biggest job interview coming up. This is at the hosptial i have dreamed of working at, on a dream unit. This program is very competative, so i feel priveleged to have made it to this stage. So i was thinking of making a packet to hand to everyone on the panel. To include a cover letter specified for that unit, my GPA, a little about why i think i would be a great fit for their unit, letters of recommendation, references, and anything else i can come up with.
So my question is, do you think this is overkill? or do you think it will help me stand out? or will i be annoying and they will be glad not to hire me? Or should i just show up without anything extra like i first planned on?
I know i am being neurotic, but i am so excited because i know i am the right person for this job.
