Yes, those are the last steps! If you got TFN, it means that your application process already has been started as you may get several emails the day you got AOR! For example I got AOR email and bio request same day! Some people got PAL before MR and some people got PAL before getting portal emails! Some people get AOR after 6 months and the second email after 10 months, on the other hand some people get AOR and second emails both after 9 months! getting AOR sooner, doesn’t mean your application process is faster! So, Don’t worry as long as you already got your TFN! Good luck!
