How Name Change impacts H4 petition

[shrirambidkar]

I am currently in US with my family and I recently changed by spouse's name (surname). With this her name on H4 petition (I-797) is not matching with her new passport.
We are also planning to apply for new H1 in March 09
Can someone please suggest me what needs to be done so that it does not impact her status and we do not have any problem in applying her H1?
