Tier 6 Early Retirement + Health Insurance (NYC)

Hey all, this might be a basic question, but I'm having trouble getting a clear answer. I called the OLR, but no one picked up, and the website just directs me to HR.

Anyway, here's my situation: I'm 57 with 12 years of full-time city service under Tier 6.

1. Early Retirement + Health Insurance: If I retire from active service this year, can I collect a reduced pension and still get "free" health insurance?
2. Working After Retirement: If I retire this year and then take a private sector job next year, will my pension and health insurance benefits remain the same (assuming the answer to question 1 is yes)?

I know these might be simple questions, but I just want to make sure before making a decision.

Thanks in advance!
