Well Shankar ,
Considering the impact on change of the farm administrator account , here are the breakup of things that will need your attention:
If the farm admin account is also used as service account for SharePoint , you are looking for trouble.
If the farm admin account is also used as SQL Service account , you are looking for trouble.
IF the farm admin account is used for running any active application pool on IIS, this can be a problem.
Also for deploying solutions you must be a farm administrator.
Farm administrator also happens to be in the local administrator group of all the servers in the database.
Farm administrator also has db_creator , db_owner rights on all WSS Content databases.
The above six points are imperative for a check when adding/removing a new farm administrator.
