Hi I am John, First timer. can anyone give accurate advice on what my wife should do?

My wife a Filipina received a fiancee visa to Britain on Nov27 2008 just 2 days after the changes in UK. We are now married in Britain (a week ago) visa expires 27 May and she is now applying for a 2 year spouse visa. The Home office require her to fill out a FLR (M) form but ask for her title (Miss or Mrs)and her full name as appears in her passport. Her passport is her maiden name, but if she gives this information I think the new ID card will show her maiden name and as a Miss.

The Philippine embassy advise that she get the "amendment" page of her green passport amended to married name but I am unsure whether Home office will notice the amendment as they may not look at the amendments page of passport.

First, does she really need to notify Philippine embassy of her marriage to British citizen and are there any implications or ramifications of not doing so or not having an ID card with her maiden name instead of married name?
What are the repercussions of having ID card in single name rather than married name. Does it HAVE to be correct? For example once her passport expires at end of 2011 will it become an issue?
Does anybody know the best thing to do?
