Your name change checklist should start with Legal Name Change (however that needs to be done where you live). Where I live, I had to fill out a form, which had to be filled out EXACTLY right, and send it in along with a fee to the appropriate government department, and the certificate arrived a couple of months later (after getting the form back once due to an error). The form also had sections that had to be filled out and signed by my doctor and my wife. Procedure where you are might be completely different. Once my name was legally changed, I could then proceed to change other documents, such as bank information, credit cards, driver's license, car ownership, insurance, health card, passports, SIN/SSN (I'm a dual citizen), etc. All documents other than SSN and health card have the new gender marker as well. I'm holding off changing my birth certificate until after surgery, because there's a fee for changing the name, and I don't want to pay the fee twice (changing the name, and then changing the gender marker after). With documents, I've found the exact order to be unimportant, but they require the legal name change certificate first. And be prepared to produce the name change certificate at the border, for instance, if all your documentation doesn't line up.
