Replacing drywall, do I need to replace the insulation?
 
1 Attachment(s)
So since the walls are so poorly done I've decided to rip them down and do them over. While I have the walls down to studs should I replace the insulation? It looks okay, I think it says R-13 3.5" which I think is standard so I seem no reason to unless I'm missing something. What else should I do(if anything) now that I have access to the studs?

Also, any suggestions for a knee-wall? I want to drywall that and remove the board look.

Insulation doesn't deteriorate! If moisture gets in there and it becomes moldy, it has to be replaced. Otherwise, its fine!
I think it would be a good idea to use a plastic vapor barrier to give it a better seal and to stop any outside air infiltration.
If you do so, the v/b on the insulation should be perforated!

Insulation should be fine but you are required to update the electrical

What jimmy said. Not sure if it is required, but I don't see an outlet on that wall. There should be at least one, depending on the width.
