Sounds like you answered your own question.
If this where my home, and I was stayin a long time, I would do what you want to do.
Remove any areas you wish and start over. Install new insulation with Kraft faced paper. Save the trim if you can and get ready for a big mess. I don't care for blown in ,but to install it blown in insulation is usually done from the outside. If there is insulation already there, you would not be able to put anymore in.
Tear out the old stuff and recycle as much as you can with the wood. Do one room at a time so you do not get overwhelmed. ...And good luck.
Let us know more as you go,we will be around.
