Jamy, honestly it wasn't that big of a deal, I went to SS office first and they have the forms online so you can print them out and have them all filled out before you even go, I went in the middle of the week around 2:00 I only waited a few minutes. I know in CA you can make appointments at the DMV I would do that if I were you, hey you have to change your address on your license and registration anyway, so you might as well get it all done at once.
Once you have those two things done its really a lot of phone calls and stuff you can do over time.
