Changing name after marriage

Hi All,

Me and Mrs got married last week, shes taken my name.

Is there a correct order to change things in? we have two copies of the marriage certificate.

So far I've come up with a list of things to be changed

Doctors
Bank
DVLA and DVSA (driving licence and V5 for her car)
Car insurance
phone bill
council tax
shes let HMRC know as she is in the process of re-registering her company.

We have been advised by loads of people to not bother updating her passport as she only had it new last year and essentially you are paying for another renewal, obviously any holidays/honeymoon would be booked under her old name so the passport matches.

Cant think of much else really, Mortgage etc is just in my name, no finance outstanding etc.
