Going with fiberglass... for ease of instalation.. etc.

Outside walls - currently has r-11 but most has come down.. so will be
replacing the stuff that has been exposed by removal of drywall. What
R value should I go with.

Go with R-asmuchasyoucan The deciding factor will be the wall cavity. You
can only fit so much material in the space of a 2 x 4 or 2 x 6. Only other
wayis to use a different mateial wiht a higher R value per inch.


Ceiling between 1st and 2nd floor - Had insulation between joists, I
have to assume it was for noise. Most has come down during
contruction, will be replacing it. What R value?

If both spaces are heated equally, it will make no real difference.



Bedroom walls - build a second floor laundry, want to sound insulate as
much as possible.. what r-value should I use in walls (regular 2x4 stud
walls)


R value has nothing to do with sound insulation. Thee are some materials
that are supposed to help though. Check out hte Owens-Corning web page for
what they offer.
