You could use validation rules to accomplish that task.

 

Regardless, the trigger would generally look like this:

 

trigger UserBlockChange on User (before update) {
  Profile userprofile = [select id,permissionsmanageusers from profile where id = :userinfo.getprofileid()];
  if(!userprofile.permissionsmanageusers) {
    for(User record:Trigger.new) {
      User oldRecord = trigger.oldMap.get(record.Id);
      if(oldRecord.FirstName!=oldRecord.FirstName) {
        record.FirstName.addError('You cannot change this value.');
      }
      if(oldRecord.LastName!=oldRecord.LastName) {
        record.FirstName.addError('You cannot change this value.');
      }
      // Other fields here
    }
  }
}

This trigger allows only administrators permission to change values.
