Just got laid off, what should I do first? (Sacramento)

They called a meeting on Thursday and 16 of us were let go. I had been there 16 years. I have read a lot of threads here and could not find my exact situation. I have a few weeks of savings and a rent payment due. Is there a checklist I should follow?

I made a short list: benefits, bills, documents, and then my résumé. One thing each day kept me steady.
