The code would look something like this. Now be aware that I don't have any data to test the code against. I added an extra parameter where you should provide the path to the workspace (eg file geodatabase). This is required to be able to use the list featureclasses correctly.
I excluded the mxd part in the beginning of the code since it is not used and requires the code to be execute
Please make a copy of your data before you execute the code!
The idea behind the code is that you collect the parameters (although i would probably use the arcpy.GetParameterAsText(#) for this purpose) and then you create a dictionary that related the fieldnames (key) to the value to be stored in that field (value). There is also a check to exclude fields from the list that are not present in the featureclass. Since Python is case sensitive a field that has the same name, but does not match case wise, will not be updated.
