You probably got a Non-Imm-O conversion (90 days) and then a retirement extension on that (+12 months). Not sure what the accident insurance card is but suspect it is the insurance banks are selling, as a condition to getting a bank account,
You are probably locked in to using the agents again when it runs out, but that is no big deal and a long time away. You will need to do 90 day reports if you stay in country over 90 days, and if you do wish to travel out a Re-Entry Permit is needed. Care to mention how much that package cost you?
