they will not give detail list for interview, I suggest

Bring everything related to you case.
Especially:
W2
Paycheck
employment letter......

For the interview itself, my suggestion:
If you have a lawyer, go with him.
If not, just relax and be professional (dress nicely),speak clearly, remember to smile:)

Take a good file binder with you, so when the officer ask for something, you can find it and pass to him quickly
Good Luck
