Dropping off my resume advice needed

I want to work at a adult care center that I went to before for my nursing clinicals. I reallly want to work there and I have applied online for an LVN/LPN Night shift.

Tomorrow morning I plan to walk in with my paper resume and let them know that I applied online.

What should I say when I walk in? Do I ask to speak to a certain person? Please give me any tips at all. I am nervous and really need the job.
I would ask to speak to the hiring manager and tell them how interested you are.
