I started the process by taking our marriage license to the DMV, and getting a new drivers license. The same day I went up to the social security office and got a new SS card. Once I had my new photo ID, I (and after much procrastination) took it to the bank and changed my name there and opened a joint account with my DH. My Credit cards were the easiest to change, I just called them, told them I had gotten married and gave them my new last name and they sent me a new card. The hardest thing to change was actually my frequent flyer accounts. I had to fax the airlines copies of my new driver's license and the marriage license. Everything else has been pretty easy.
