You got it all
The advice on the link you provided is just great.
Getting from there I would not miss Serra do Rio do Rastro (google image it and yyou will see) one ofnthe 10 most beautiful roads in the world according to an online rider survey (you can google for tha link also).
If you change your mind and head north towards Sao Paulo or Rio do let me know. BTW going back to that post if you do Sao Paulo to Rio make sure to use the coast, not the BR1166 highway! Why? Google image for Angra dos Reis or Paraty and you have an answer besides 116 = trucks, trucks,mand more trucks!
Do let me know if you need more help!
