  You could use the extension CiviRules to do that.
  
  You need to set up two different Rules, one for each process.
  
  Select a trigger and condition with your requirements (group contact is added, and contact is changed, would be the triggers I think)
  
  Dependent on your preference, you could create one of these actions:
  
  * a scheduled activity assigned to a backend staff
  * a tag (that could be shown in a report on your dashboard)
  * send you an email (then you need to install the Email API as well, and choose to send email to alternate email adress)
  * send you an sms (then you need to install the SMS API as well, and choose to send sms to alternate phone number)
